This code is in the Public +dnl Domain. +dnl +dnl This test is for network applications that need socket() and +dnl gethostbyname() -ish functions. Under Solaris, those applications need to +dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with +dnl "-lsocket" because libsocket.a breaks a number of things (for instance: +dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of +dnl IRIX). +dnl +dnl Unfortunately, many application developers are not aware of this, and +dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is +dnl also easy to write tests that cause -lnsl to be used under operating +dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which +dnl uses -lnsl for TLI. +dnl +dnl This test exists so that every application developer does not test this in +dnl a different, and subtly broken fashion. +dnl +dnl It has been argued that this test should be broken up into two seperate +dnl tests, one for the resolver libraries, and one for the libraries necessary +dnl for using Sockets API. Unfortunately, the two are carefully intertwined and +dnl allowing the autoconf user to use them independantly potentially results in +dnl unfortunate ordering dependancies -- as such, such component macros would +dnl have to carefully use indirection and be aware if the other components were +dnl executed. Since other autoconf macros do not go to this trouble, and almost +dnl no applications use sockets without the resolver, this complexity has not +dnl been implemented. +dnl +dnl The check for libresolv is in case you are attempting to link statically +dnl and happen to have a libresolv.a lying around (and no libnsl.a). +dnl +AC_DEFUN(AC_LIBRARY_NET, [ + # Most operating systems have gethostbyname() in the default searched + # libraries (i.e. libc): + AC_CHECK_FUNC(gethostbyname, , + # Some OSes (eg.

archive using +.Xr compress 1 +format. +.It Fl 6 +Process old-style +.Nm +format archives. +.El +.It Fl p , -pass-through +Copy files from one location to another in a single pass. +The list of files to copy are read from standard input and +written out to a directory relative to the specified +.Ar directory +argument. +.Bl -tag -width Ds +.It Fl a +Reset the access times on files that have been copied. +.It Fl d +Create any intermediate directories as needed to write +the files at the new location. +.It Fl l , -link +When possible, link files rather than creating an +extra copy. +.It Fl L , -dereference +Follow symbolic links. +.It Fl m , -preserve-modification-time +Restore modification times on files. +.It Fl u , -unconditional +Overwrite files even when the original file being copied is +older than the one that will be overwritten. +.It Fl v , -verbose +Be verbose about operations. +List filenames as they are copied. +.It Fl -force-local +Do not interpret filenames that contain a +.Sq \&: +as remote files. +.It Fl -insecure +Normally +.Nm +ignores filenames that contain +.Sq .. +as a path component.

Typical examples of these are files created by dbm + * variants (.pag files). While the file size of these files are huge, the + * actual storage is quite small (the files are sparse). The problem is + * the holes read as all zeros so are probably stored on the archive that + * way (there is no way to determine if the file block is really a hole, + * we only know that a file block of all zero's can be a hole). + * At this writing, no major archive format knows how to archive files + * with holes. However, on extraction (or during copy, -rw) we have to + * deal with these files. Without detecting the holes, the files can + * consume a lot of file space if just written to disk. This replacement + * for write when passed the basic allocation size of a file system block, + * uses lseek whenever it detects the input data is all 0 within that + * file block. In more detail, the strategy is as follows: + * While the input is all zero keep doing an lseek. Keep track of when we + * pass over file block boundaries. Only write when we hit a non zero + * input. once we have written a file block, we continue to write it to + * the end (we stop looking at the input). When we reach the start of the + * next file block, start checking for zero blocks again. Working on file + * block boundaries significantly reduces the overhead when copying files + * that are NOT very sparse. This overhead (when compared to a write) is + * almost below the measurement resolution on many systems. Without it, + * files with holes cannot be safely copied. It does has a side effect as + * it can put holes into files that did not have them before, but that is + * not a problem since the file contents are unchanged (in fact it saves + * file space). (Except on paging files for diskless clients. But since we + * cannot determine one of those file from here, we ignore them). If this + * ever ends up on a system where CTG files are supported and the holes + * are not desired, just do a conditional test in those routines that + * call file_write() and have it call write() instead. BEFORE CLOSING THE + * FILE, make sure to call file_flush() when the last write finishes with + * an empty block. A lot of file systems will not create an lseek hole at + * the end.

file is of the form: +.Ar [[user@]host:]file +then the archive will be processed using +.Xr rmt 8 . +.Pp +.Nm +operation is independent of the specific archive format, +and supports a wide variety of different archive formats. +A list of supported archive formats can be found under the description of the +.Fl x +option. +.Pp +The presence of the +.Fl r +and the +.Fl w +options specifies which of the following functional modes +.Nm +will operate under: +.Em list , read , write , +and +.Em copy . +.Bl -tag -width 6n +.It Aq none +.Em List . +.Nm +will write to +.Dv standard output +a table of contents of the members of the archive file read from +.Dv standard input , +whose pathnames match the specified +.Ar patterns . +The table of contents contains one filename per line +and is written using single line buffering. +.It Fl r +.Em Read . +.Nm +extracts the members of the archive file read from the +.Dv standard input , +with pathnames matching the specified +.Ar patterns . +The archive format and blocking is automatically determined on input. +When an extracted file is a directory, the entire file hierarchy +rooted at that directory is extracted. +All extracted files are created relative to the current file hierarchy. +The setting of ownership, access and modification times, and file mode of +the extracted files are discussed in more detail under the +.Fl p +option. +.It Fl w +.Em Write . +.Nm +writes an archive containing the +.Ar file +operands to +.Dv standard output +using the specified archive format. +When no +.Ar file +operands are specified, a list of files to copy with one per line is read from +.Dv standard input . +When a +.Ar file +operand is also a directory, the entire file hierarchy rooted +at that directory will be included. +.It Fl r Fl w +.Em Copy . +.Nm +copies the +.Ar file +operands to the destination +.Ar directory . +When no +.Ar file +operands are specified, a list of files to copy with one per line is read from +the +.Dv standard input . +When a +.Ar file +operand is also a directory the entire file +hierarchy rooted at that directory will be included. +The effect of the +.Em copy +is as if the copied files were written to an archive file and then +subsequently extracted, except that there may be hard links between +the original and the copied files (see the +.Fl l +option below). +.Pp +.Em Warning : +The destination +.Ar directory +must not be one of the +.Ar file +operands or a member of a file hierarchy rooted at one of the +.Ar file +operands. +The result of a +.Em copy +under these conditions is unpredictable. +.El +.Pp +While processing a damaged archive during a +.Em read +or +.Em list +operation, +.Nm +will attempt to recover from media defects and will search through the archive +to locate and process the largest number of archive members possible (see the +.Fl E +option for more details on error handling). +.Sh OPERANDS +The +.Ar directory +operand specifies a destination directory pathname. +If the +.Ar directory +operand does not exist, or it is not writable by the user, +or it is not of type directory, +.Nm +will exit with a non-zero exit status. +.Pp +The +.Ar pattern +operand is used to select one or more pathnames of archive members. +Archive members are selected using the pattern matching notation described +by +.Xr fnmatch 3 . +When the +.Ar pattern +operand is not supplied, all members of the archive will be selected. +When a +.Ar pattern +matches a directory, the entire file hierarchy rooted at that directory will +be selected. +When a +.Ar pattern +operand does not select at least one archive member, +.Nm +will write these +.Ar pattern +operands in a diagnostic message to +.Dv standard error +and then exit with a non-zero exit status. +.Pp +The +.Ar file +operand specifies the pathname of a file to be copied or archived. +When a +.Ar file +operand does not select at least one archive member, +.Nm +will write these +.Ar file +operand pathnames in a diagnostic message to +.Dv standard error +and then exit with a non-zero exit status. +.Sh OPTIONS +The following options are supported: +.Bl -tag -width 4n +.It Fl r +Read an archive file from +.Dv standard input +and extract the specified +.Ar files . +If any intermediate directories are needed in order to extract an archive +member, these directories will be created as if +.Xr mkdir 2 +was called with the bitwise inclusive +.Dv OR +of +.Dv S_IRWXU , S_IRWXG , +and +.Dv S_IRWXO +as the mode argument. +When the selected archive format supports the specification of linked +files and these files cannot be linked while the archive is being extracted, +.Nm +will write a diagnostic message to +.Dv standard error +and exit with a non-zero exit status at the completion of operation. +.It Fl w +Write files to the +.Dv standard output +in the specified archive format. +When no +.Ar file +operands are specified, +.Dv standard input +is read for a list of pathnames with one per line without any leading or +trailing +.Aq blanks . +.It Fl a +Append +.Ar files +to the end of an archive that was previously written. +If an archive format is not specified with a +.Fl x +option, the format currently being used in the archive will be selected. +Any attempt to append to an archive in a format different from the +format already used in the archive will cause +.Nm +to exit immediately +with a non-zero exit status. +The blocking size used in the archive volume where writing starts +will continue to be used for the remainder of that archive volume. +.Pp +.Em Warning : +Many storage devices are not able to support the operations necessary +to perform an append operation. +Any attempt to append to an archive stored on such a device may damage the +archive or have other unpredictable results. +Tape drives in particular are more likely to not support an append operation. +An archive stored in a regular file system file or on a disk device will +usually support an append operation. +.It Fl b Ar blocksize +When +.Em writing +an archive, +block the output at a positive decimal integer number of +bytes per write to the archive file. +The +.Ar blocksize +must be a multiple of 512 bytes with a maximum of 32256 bytes. +A +.Ar blocksize +can end with +.Li k +or +.Li b +to specify multiplication by 1024 (1K) or 512, respectively. +A pair of +.Ar blocksizes +can be separated by +.Li x +to indicate a product. +A specific archive device may impose additional restrictions on the size +of blocking it will support. +When blocking is not specified, the default +.Ar blocksize +is dependent on the specific archive format being used (see the +.Fl x +option). +.It Fl c +Match all file or archive members +.Em except +those specified by the +.Ar pattern +and +.Ar file +operands. +.It Fl d +Cause files of type directory being copied or archived, or archive members of +type directory being extracted, to match only the directory file or archive +member and not the file hierarchy rooted at the directory. +.It Fl f Ar archive +Specify +.Ar archive +as the pathname of the input or output archive, overriding the default +.Dv standard input +(for +.Em list +and +.Em read ) +or +.Dv standard output +(for +.Em write ) . +A single archive may span multiple files and different archive devices. +When required, +.Nm +will prompt for the pathname of the file or device of the next volume in the +archive. +.It Fl i +Interactively rename files or archive members. +For each archive member matching a +.Ar pattern +operand or each file matching a +.Ar file +operand, +.Nm +will prompt to +.Pa /dev/tty +giving the name of the file, its file mode and its modification time. +.Nm +will then read a line from +.Pa /dev/tty . +If this line is blank, the file or archive member is skipped. +If this line consists of a single period, the +file or archive member is processed with no modification to its name. +Otherwise, its name is replaced with the contents of the line. +.Nm +will immediately exit with a non-zero exit status if +.Aq Dv EOF +is encountered when reading a response or if +.Pa /dev/tty +cannot be opened for reading and writing. +.It Fl j +Use +.Xr bzip2 1 +for compression when reading or writing archive files. +.It Fl k +Do not overwrite existing files. +.It Fl l +Link files. +(The letter ell). +In the +.Em copy +mode +.Fl ( r +.Fl w ) , +hard links are made between the source and destination file hierarchies +whenever possible. +.It Fl n +Select the first archive member that matches each +.Ar pattern +operand. +No more than one archive member is matched for each +.Ar pattern . +When members of type directory are matched, the file hierarchy rooted at that +directory is also matched (unless +.Fl d +is also specified). +.It Fl o Ar options +Information to modify the algorithm for extracting or writing archive files +which is specific to the archive format specified by +.Fl x . +In general, +.Ar options +take the form: +.Cm name=value +.It Fl p Ar string +Specify one or more file characteristic options (privileges). +The +.Ar string +option-argument is a string specifying file characteristics to be retained or +discarded on extraction. +The string consists of the specification characters +.Cm a , e , f , +.Cm m , o , +and +.Cm p . +Multiple characteristics can be concatenated within the same string +and multiple +.Fl p +options can be specified. +The meaning of the specification characters are as follows: +.Bl -tag -width 2n +.It Cm a +Do not preserve file access times. +By default, file access times are preserved whenever possible. +.It Cm e +.Sq Preserve everything , +the user ID, group ID, file mode bits, +file access time, and file modification time. +This is intended to be used by +.Em root , +someone with all the appropriate privileges, in order to preserve all +aspects of the files as they are recorded in the archive. +The +.Cm e +flag is the sum of the +.Cm o +and +.Cm p +flags. +.\" .It Cm f +.\" Do not preserve file flags. +.\" By default, file flags are preserved whenever possible. +.It Cm m +Do not preserve file modification times. +By default, file modification times are preserved whenever possible. +.It Cm o +Preserve the user ID and group ID. +.It Cm p +.Sq Preserve +the file mode bits. +This is intended to be used by a +.Em user +with regular privileges who wants to preserve all aspects of the file other +than the ownership. +The file times are preserved by default, but two other flags are offered to +disable this and use the time of extraction instead. +.El +.Pp +In the preceding list, +.Sq preserve +indicates that an attribute stored in the archive is given to the +extracted file, subject to the permissions of the invoking +process. +Otherwise the attribute of the extracted file is determined as +part of the normal file creation action. +If neither the +.Cm e +nor the +.Cm o +specification character is specified, or the user ID and group ID are not +preserved for any reason, +.Nm +will not set the +.Dv S_ISUID +.Em ( setuid ) +and +.Dv S_ISGID +.Em ( setgid ) +bits of the file mode. +If the preservation of any of these items fails for any reason, +.Nm +will write a diagnostic message to +.Dv standard error . +Failure to preserve these items will affect the final exit status, +but will not cause the extracted file to be deleted. +If the file characteristic letters in any of the string option-arguments are +duplicated or conflict with each other, the one(s) given last will take +precedence. +For example, if +.Dl Fl p Ar eme +is specified, file modification times are still preserved. +.It Fl s Ar replstr +Modify the file or archive member names specified by the +.Ar pattern +or +.Ar file +operands according to the substitution expression +.Ar replstr , +using the syntax of the +.Xr ed 1 +utility regular expressions. +The format of these regular expressions are: +.Dl /old/new/[gp] +As in +.Xr ed 1 , +.Cm old +is a basic regular expression and +.Cm new +can contain an ampersand (\*[Am]), \\n (where n is a digit) back-references, +or subexpression matching. +The +.Cm old +string may also contain +.Aq Dv newline +characters. +Any non-null character can be used as a delimiter (/ is shown here). +Multiple +.Fl s +expressions can be specified. +The expressions are applied in the order they are specified on the +command line, terminating with the first successful substitution. +The optional trailing +.Cm g +continues to apply the substitution expression to the pathname substring +which starts with the first character following the end of the last successful +substitution. +The first unsuccessful substitution stops the operation of the +.Cm g +option. +The optional trailing +.Cm p +will cause the final result of a successful substitution to be written to +.Dv standard error +in the following format: +.Dl Ao "original pathname" Ac \*[Gt]\*[Gt] Ao "new pathname" Ac +File or archive member names that substitute to the empty string +are not selected and will be skipped. +.It Fl t +Reset the access times of any file or directory read or accessed by +.Nm +to be the same as they were before being read or accessed by +.Nm , +if the user has the appropriate permissions required by +.Xr utime 3 . +.It Fl u +Ignore files that are older (having a less recent file modification time) +than a pre-existing file or archive member with the same name. +During +.Em read , +an archive member with the same name as a file in the file system will be +extracted if the archive member is newer than the file. +During +.Em write , +a file system member with the same name as an archive member will be +written to the archive if it is newer than the archive member. +During +.Em copy , +the file in the destination hierarchy is replaced by the file in the source +hierarchy or by a link to the file in the source hierarchy if the file in +the source hierarchy is newer. +.It Fl v +During a +.Em list +operation, produce a verbose table of contents using the format of the +.Xr ls 1 +utility with the +.Fl l +option. +For pathnames representing a hard link to a previous member of the archive, +the output has the format: +.Dl Ao "ls -l listing" Ac == Ao "link name" Ac +Where +.Aq "ls -l listing" +is the output format specified by the +.Xr ls 1 +utility when used with the +.Fl l +option. +Otherwise for all the other operational modes +.Em ( read , write , +and +.Em copy ) , +pathnames are written and flushed to +.Dv standard error +without a trailing +.Aq Dv newline +as soon as processing begins on that file or +archive member. +The trailing +.Aq Dv newline , +is not buffered, and is written only after the file has been read or written. +.It Fl x Ar format +Specify the output archive format, with the default format being +.Ar ustar . +.Nm +currently supports the following formats: +.Bl -tag -width "sv4cpio" +.It Ar cpio +The extended cpio interchange format specified in the +.St -p1003.2 +standard. +The default blocksize for this format is 5120 bytes. +Inode and device information about a file (used for detecting file hard links +by this format) which may be truncated by this format is detected by +.Nm +and is repaired. +.It Ar bcpio +The old binary cpio format. +The default blocksize for this format is 5120 bytes. +This format is not very portable and should not be used when other formats +are available. +Inode and device information about a file (used for detecting file hard links +by this format) which may be truncated by this format is detected by +.Nm +and is repaired. +.It Ar sv4cpio +The +.At V.4 +cpio. +The default blocksize for this format is 5120 bytes. +Inode and device information about a file (used for detecting file hard links +by this format) which may be truncated by this format is detected by +.Nm +and is repaired. +.It Ar sv4crc +The +.At V.4 +cpio with file crc checksums. +The default blocksize for this format is 5120 bytes. +Inode and device information about a file (used for detecting file hard links +by this format) which may be truncated by this format is detected by +.Nm +and is repaired. +.It Ar tar +The old +.Bx +tar format as found in +.Bx 4.3 . +The default blocksize for this format is 10240 bytes. +Pathnames stored by this format must be 100 characters or less in length. +Only +.Em regular +files, +.Em hard links , soft links , +and +.Em directories +will be archived (other file system types are not supported). +For backwards compatibility with even older tar formats, a +.Fl o +option can be used when writing an archive to omit the storage of directories. +This option takes the form: +.Dl Fl o Cm write_opt=nodir +.It Ar ustar +The extended tar interchange format specified in the +.St -p1003.2 +standard. +The default blocksize for this format is 10240 bytes. +Pathnames stored by this format must be 250 characters or less in length. +.El +.Pp +.Nm +will detect and report any file that it is unable to store or extract +as the result of any specific archive format restrictions. +The individual archive formats may impose additional restrictions on use. +Typical archive format restrictions include (but are not limited to): +file pathname length, file size, link pathname length and the type of the file. +.It Fl z +Use +.Xr gzip 1 +compression, when reading or writing archive files. +.It Fl A +Do not strip leading `/'s from file names. +.It Fl B Ar bytes +Limit the number of bytes written to a single archive volume to +.Ar bytes . +The +.Ar bytes +limit can end with +.Li m , +.Li k , +or +.Li b +to specify multiplication by 1048576 (1M), 1024 (1K) or 512, respectively. +A pair of +.Ar bytes +limits can be separated by +.Li x +to indicate a product. +.Pp +.Em Warning : +Only use this option when writing an archive to a device which supports +an end of file read condition based on last (or largest) write offset +(such as a regular file or a tape drive). +The use of this option with a floppy or hard disk is not recommended. +.It Fl D +This option is the same as the +.Fl u +option, except that the file inode change time is checked instead of the +file modification time. +The file inode change time can be used to select files whose inode information +(e.g. uid, gid, etc.) is newer than a copy of the file in the destination +.Ar directory . +.It Fl E Ar limit +Limit the number of consecutive read faults while trying to read a flawed +archives to +.Ar limit . +With a positive +.Ar limit , +.Nm +will attempt to recover from an archive read error and will +continue processing starting with the next file stored in the archive. +A +.Ar limit +of 0 will cause +.Nm +to stop operation after the first read error is detected on an archive volume. +A +.Ar limit +of +.Li NONE +will cause +.Nm +to attempt to recover from read errors forever. +The default +.Ar limit +is a small positive number of retries. +.Pp +.Em Warning : +Using this option with +.Li NONE +should be used with extreme caution as +.Nm +may get stuck in an infinite loop on a very badly flawed archive. +.It Fl G Ar group +Select a file based on its +.Ar group +name, or when starting with a +.Cm # , +a numeric gid. +A '\\' can be used to escape the +.Cm # . +Multiple +.Fl G +options may be supplied and checking stops with the first match. +.It Fl H +Follow only command line symbolic links while performing a physical file +system traversal. +.It Fl L +Follow all symbolic links to perform a logical file system traversal. +.It Fl M +During a +.Em write +or +.Em copy +operation, treat the list of files on +.Dv standard input +as an +.Xr mtree 8 +.Sq specfile +specification, and write or copy only those items in the specfile. +.Pp +If the file exists in the underlying file system, its permissions and +modification time will be used unless specifically overridden by the specfile. +An error will be raised if the type of entry in the specfile conflicts +with that of an existing file. +A directory entry that is marked +.Sq Sy optional +will not be copied (even though its contents will be). +.Pp +Otherwise, the entry will be +.Sq faked-up , +and it is necessary to specify at least the following parameters +in the specfile: +.Sy type , +.Sy mode , +.Sy gname +or +.Sy gid , +and +.Sy uname +or +.Sy uid , +.Sy device +(in the case of block or character devices), and +.Sy link +(in the case of symbolic links). +If +.Sy time +isn't provided, the current time will be used. +A +.Sq faked-up +entry that is marked +.Sq Sy optional +will not be copied. +.It Fl N Ar dbdir +Except for lookups for the +.Fl G +and +.Fl U +options, +use the user database text file +.Pa master.passwd +and group database text file +.Pa group +from +.Ar dbdir , +rather than using the results from the system's +.Xr getpwnam 3 +and +.Xr getgrnam 3 +(and related) library calls. +.It Fl O +Force the archive to be one volume. +If a volume ends prematurely, +.Nm +will not prompt for a new volume. +This option can be useful for +automated tasks where error recovery cannot be performed by a human. +.It Fl P +Do not follow symbolic links, perform a physical file system traversal. +This is the default mode. +.It Fl T Ar [from_date][,to_date][/[c][m]] +Allow files to be selected based on a file modification or inode change +time falling within a specified time range of +.Ar from_date +to +.Ar to_date +(the dates are inclusive). +If only a +.Ar from_date +is supplied, all files with a modification or inode change time +equal to or younger are selected. +If only a +.Ar to_date +is supplied, all files with a modification or inode change time +equal to or older will be selected. +When the +.Ar from_date +is equal to the +.Ar to_date , +only files with a modification or inode change time of exactly that +time will be selected. +.Pp +When +.Nm +is in the +.Em write +or +.Em copy +mode, the optional trailing field +.Ar [c][m] +can be used to determine which file time (inode change, file modification or +both) are used in the comparison. +If neither is specified, the default is to use file modification time only. +The +.Ar m +specifies the comparison of file modification time (the time when +the file was last written). +The +.Ar c +specifies the comparison of inode change time (the time when the file +inode was last changed; e.g. a change of owner, group, mode, etc). +When +.Ar c +and +.Ar m +are both specified, then the modification and inode change times are +both compared. +The inode change time comparison is useful in selecting files whose +attributes were recently changed or selecting files which were recently +created and had their modification time reset to an older time (as what +happens when a file is extracted from an archive and the modification time +is preserved). +Time comparisons using both file times is useful when +.Nm +is used to create a time based incremental archive (only files that were +changed during a specified time range will be archived). +.Pp +A time range is made up of six different fields and each field must contain two +digits. +The format is: +.Dl [[[[[cc]yy]mm]dd]hh]mm[\&.ss] +Where +.Cm cc +is the first two digits of the year (the century), +.Cm yy +is the last two digits of the year, +the first +.Cm mm +is the month (from 01 to 12), +.Cm dd +is the day of the month (from 01 to 31), +.Cm hh +is the hour of the day (from 00 to 23), +the second +.Cm mm +is the minute (from 00 to 59), +and +.Cm ss +is the seconds (from 00 to 61). +Only the minute field +.Cm mm +is required; the others will default to the current system values. +The +.Cm ss +field may be added independently of the other fields. +If the century is not specified, it defaults to 1900 for +years between 69 and 99, or 2000 for years between 0 and 68. +Time ranges are relative to the current time, so +.Dl Fl T Ar 1234/cm +would select all files with a modification or inode change time +of 12:34 PM today or later. +Multiple +.Fl T +time range can be supplied and checking stops with the first match. +.It Fl U Ar user +Select a file based on its +.Ar user +name, or when starting with a +.Cm # , +a numeric uid. +A '\\' can be used to escape the +.Cm # . +Multiple +.Fl U +options may be supplied and checking stops with the first match. +.It Fl X +When traversing the file hierarchy specified by a pathname, +do not descend into directories that have a different device ID. +See the +.Li st_dev +field as described in +.Xr stat 2 +for more information about device ID's. +.It Fl Y +This option is the same as the +.Fl D +option, except that the inode change time is checked using the +pathname created after all the file name modifications have completed. +.It Fl Z +This option is the same as the +.Fl u +option, except that the modification time is checked using the +pathname created after all the file name modifications have completed. +.It Fl -force-local +Do not interpret filenames that contain a `:' as remote files. +.It Fl -insecure +Normally +.Nm +ignores filenames that contain `..' as a path component. With this option, +files that contain `..' can be processed. +.El +.Pp +The options that operate on the names of files or archive members +.Fl ( c , +.Fl i , +.Fl n , +.Fl s , +.Fl u , +.Fl v , +.Fl D , +.Fl G , +.Fl T , +.Fl U , +.Fl Y , +and +.Fl Z ) +interact as follows. +.Pp +When extracting files during a +.Em read +operation, archive members are +.Sq selected , +based only on the user specified pattern operands as modified by the +.Fl c , +.Fl n , +.Fl u , +.Fl D , +.Fl G , +.Fl T , +.Fl U +options. +Then any +.Fl s +and +.Fl i +options will modify in that order, the names of these selected files. +Then the +.Fl Y +and +.Fl Z +options will be applied based on the final pathname. +Finally the +.Fl v +option will write the names resulting from these modifications. +.Pp +When archiving files during a +.Em write +operation, or copying files during a +.Em copy +operation, archive members are +.Sq selected , +based only on the user specified pathnames as modified by the +.Fl n , +.Fl u , +.Fl D , +.Fl G , +.Fl T , +and +.Fl U +options (the +.Fl D +option only applies during a copy operation). +Then any +.Fl s +and +.Fl i +options will modify in that order, the names of these selected files. +Then during a +.Em copy +operation the +.Fl Y +and the +.Fl Z +options will be applied based on the final pathname. +Finally the +.Fl v +option will write the names resulting from these modifications. +.Pp +When one or both of the +.Fl u +or +.Fl D +options are specified along with the +.Fl n +option, a file is not considered selected unless it is newer +than the file to which it is compared. +.Sh EXAMPLES +The command: +.Dl pax -w -f /dev/rst0 \&. +copies the contents of the current directory to the device +.Pa /dev/rst0 . +.Pp +The command: +.Dl pax -v -f filename +gives the verbose table of contents for an archive stored in +.Pa filename . +.Pp +The following commands: +.Dl mkdir newdir +.Dl cd olddir +.Dl pax -rw -pp .\ ../newdir +will copy the entire +.Pa olddir +directory hierarchy to +.Pa newdir , +preserving permissions and access times. +.Pp +When running as root, one may also wish to preserve file +ownership when copying directory trees. +This can be done with the following commands: +.Dl cd olddir +.Dl pax -rw -pe .\ .../newdir +which will copy the contents of +.Pa olddir +into +.Pa .../newdir , +preserving ownership, permissions and access times. +.Pp +The command: +.Dl pax -r -s ',^//*usr//*,,' -f a.pax +reads the archive +.Pa a.pax , +with all files rooted in ``/usr'' into the archive extracted relative to the +current directory. +.Pp +The command: +.Dl pax -rw -i .\ dest_dir +can be used to interactively select the files to copy from the current +directory to +.Pa dest_dir . +.Pp +The command: +.Dl pax -r -pe -U root -G bin -f a.pax +will extract all files from the archive +.Pa a.pax +which are owned by +.Em root +with group +.Em bin +and will preserve all file permissions. +.Pp +The command: +.Dl pax -r -w -v -Y -Z home /backup +will update (and list) only those files in the destination directory +.Pa /backup +which are older (less recent inode change or file modification times) than +files with the same name found in the source file tree +.Pa home . +.Sh ERRORS +.Nm +will exit with one of the following values: +.Bl -tag -width 2n +.It 0 +All files were processed successfully. +.It 1 +An error occurred. +.El +.Pp +Whenever +.Nm +cannot create a file or a link when reading an archive or cannot +find a file when writing an archive, or cannot preserve the user ID, +group ID, or file mode when the +.Fl p +option is specified, a diagnostic message is written to +.Dv standard error +and a non-zero exit status will be returned, but processing will continue. +In the case where pax cannot create a link to a file, +.Nm +will not create a second copy of the file. +.Pp +If the extraction of a file from an archive is prematurely terminated by +a signal or error, +.Nm +may have only partially extracted a file the user wanted. +Additionally, the file modes of extracted files and directories +may have incorrect file bits, and the modification and access times may be +wrong. +.Pp +If the creation of an archive is prematurely terminated by a signal or error, +.Nm +may have only partially created the archive which may violate the specific +archive format specification. +.Pp +If while doing a +.Em copy , +.Nm +detects a file is about to overwrite itself, the file is not copied, +a diagnostic message is written to +.Dv standard error +and when +.Nm +completes it will exit with a non-zero exit status.

Damaged sections of archives + * are detected and avoided if possible. Attempts will be made to resync + * archive read operations even with badly damaged media. + * 1.2 Blocksize requirements are not strictly enforced on archive read. + * Tapes which have variable sized records can be read without errors. + * 1.3 The user can specify via the non-standard option flag -E if error + * resync operation should stop on a media error, try a specified number + * of times to correct, or try to correct forever. + * 1.4 Sparse files (lseek holes) stored on the archive (but stored with blocks + * of all zeros will be restored with holes appropriate for the target + * filesystem + * 1.5 The user is notified whenever something is found during archive + * read operations which violates spec (but the read will continue). + * 1.6 Multiple archive volumes can be read and may span over different + * archive devices + * 1.7 Rigidly restores all file attributes exactly as they are stored on the + * archive. + * 1.8 Modification change time ranges can be specified via multiple -T + * options. These allow a user to select files whose modification time + * lies within a specific time range. + * 1.9 Files can be selected based on owner (user name or uid) via one or more + * -U options. + * 1.10 Files can be selected based on group (group name or gid) via one o + * more -G options. + * 1.11 File modification time can be checked against existing file after + * name modification (-Z) + * + * 2 WRITE ENHANCEMENTS + * 2.1 Write operation will stop instead of allowing a user to create a flawed + * flawed archive (due to any problem). + * 2.2 Archives written by pax are forced to strictly conform to both the + * archive and pax the spceific format specifications. + * 2.3 Blocking size and format is rigidly enforced on writes. + * 2.4 Formats which may exhibit header overflow problems (they have fields + * too small for large file systems, such as inode number storage), use + * routines designed to repair this problem. These techniques still + * conform to both pax and format specifications, but no longer truncate + * these fields. This removes any restrictions on using these archive + * formats on large file systems. + * 2.5 Multiple archive volumes can be written and may span over different + * archive devices + * 2.6 A archive volume record limit allows the user to specify the number + * of bytes stored on an archive volume. When reached the user is + * prompted for the next archive volume. This is specified with the + * non-standard -B flag. The limit is rounded up to the next blocksize. + * 2.7 All archive padding during write use zero filled sections. This makes + * it much easier to pull data out of flawed archive during read + * operations. + * 2.8 Access time reset with the -t applies to all file nodes (including + * directories). + * 2.9 Symbolic links can be followed with -L (optional in the spec). + * 2.10 Modification or inode change time ranges can be specified via + * multiple -T options.

If the archive file is of the form: + _[_[_u_s_e_r_@_]_h_o_s_t_:_]_f_i_l_e then the archive will be processed using rmt(8). + + ppaaxx operation is independent of the specific archive format, and supports + a wide variety of different archive formats. A list of supported archive + formats can be found under the description of the --xx option. + + The presence of the --rr and the --ww options specifies which of the follow- + ing functional modes ppaaxx will operate under: _l_i_s_t, _r_e_a_d, _w_r_i_t_e, and _c_o_p_y. + + <none> _L_i_s_t. ppaaxx will write to standard output a table of contents of + the members of the archive file read from standard input, whose + pathnames match the specified _p_a_t_t_e_r_n_s. The table of contents + contains one filename per line and is written using single line + buffering. + + --rr _R_e_a_d. ppaaxx extracts the members of the archive file read from the + standard input, with pathnames matching the specified _p_a_t_t_e_r_n_s. + The archive format and blocking is automatically determined on + input. When an extracted file is a directory, the entire file + hierarchy rooted at that directory is extracted. All extracted + files are created relative to the current file hierarchy. The + setting of ownership, access and modification times, and file + mode of the extracted files are discussed in more detail under + the --pp option. + + --ww _W_r_i_t_e. ppaaxx writes an archive containing the _f_i_l_e operands to + standard output using the specified archive format. When no _f_i_l_e + operands are specified, a list of files to copy with one per line + is read from standard input. When a _f_i_l_e operand is also a di- + rectory, the entire file hierarchy rooted at that directory will + be included. + + --rr --ww _C_o_p_y. ppaaxx copies the _f_i_l_e operands to the destination _d_i_r_e_c_t_o_r_y. + When no _f_i_l_e operands are specified, a list of files to copy with + one per line is read from the standard input. When a _f_i_l_e + operand is also a directory the entire file hierarchy rooted at + that directory will be included. The effect of the _c_o_p_y is as if + the copied files were written to an archive file and then subse- + quently extracted, except that there may be hard links between + the original and the copied files (see the --ll option below). + + _W_a_r_n_i_n_g: The destination _d_i_r_e_c_t_o_r_y must not be one of the _f_i_l_e + operands or a member of a file hierarchy rooted at one of the + _f_i_l_e operands. The result of a _c_o_p_y under these conditions is + unpredictable. + + While processing a damaged archive during a _r_e_a_d or _l_i_s_t operation, ppaaxx + will attempt to recover from media defects and will search through the + archive to locate and process the largest number of archive members pos- + sible (see the --EE option for more details on error handling). + +OOPPEERRAANNDDSS + The _d_i_r_e_c_t_o_r_y operand specifies a destination directory pathname. If the + _d_i_r_e_c_t_o_r_y operand does not exist, or it is not writable by the user, or + it is not of type directory, ppaaxx will exit with a non-zero exit status. + + The _p_a_t_t_e_r_n operand is used to select one or more pathnames of archive + members. Archive members are selected using the pattern matching nota- + tion described by fnmatch(3). When the _p_a_t_t_e_r_n operand is not supplied, + all members of the archive will be selected. When a _p_a_t_t_e_r_n matches a + directory, the entire file hierarchy rooted at that directory will be se- + lected. When a _p_a_t_t_e_r_n operand does not select at least one archive mem- + ber, ppaaxx will write these _p_a_t_t_e_r_n operands in a diagnostic message to + standard error and then exit with a non-zero exit status. + + The _f_i_l_e operand specifies the pathname of a file to be copied or + archived. When a _f_i_l_e operand does not select at least one archive mem- + ber, ppaaxx will write these _f_i_l_e operand pathnames in a diagnostic message + to standard error and then exit with a non-zero exit status. + +OOPPTTIIOONNSS + The following options are supported: + + --rr Read an archive file from standard input and extract the specified + _f_i_l_e_s. If any intermediate directories are needed in order to ex- + tract an archive member, these directories will be created as if + mkdir(2) was called with the bitwise inclusive OR of S_IRWXU, + S_IRWXG, and S_IRWXO as the mode argument. When the selected + archive format supports the specification of linked files and these + files cannot be linked while the archive is being extracted, ppaaxx + will write a diagnostic message to standard error and exit with a + non-zero exit status at the completion of operation. + + --ww Write files to the standard output in the specified archive format. + When no _f_i_l_e operands are specified, standard input is read for a + list of pathnames with one per line without any leading or trailing + <blanks>. + + --aa Append _f_i_l_e_s to the end of an archive that was previously written. + If an archive format is not specified with a --xx option, the format + currently being used in the archive will be selected. Any attempt + to append to an archive in a format different from the format al- + ready used in the archive will cause ppaaxx to exit immediately with a + non-zero exit status. The blocking size used in the archive volume + where writing starts will continue to be used for the remainder of + that archive volume. + + _W_a_r_n_i_n_g: Many storage devices are not able to support the opera- + tions necessary to perform an append operation. Any attempt to ap- + pend to an archive stored on such a device may damage the archive + or have other unpredictable results. Tape drives in particular are + more likely to not support an append operation. An archive stored + in a regular file system file or on a disk device will usually sup- + port an append operation. + + --bb _b_l_o_c_k_s_i_z_e + When _w_r_i_t_i_n_g an archive, block the output at a positive decimal in- + teger number of bytes per write to the archive file. The _b_l_o_c_k_s_i_z_e + must be a multiple of 512 bytes with a maximum of 32256 bytes. A + _b_l_o_c_k_s_i_z_e can end with k or b to specify multiplication by 1024 + (1K) or 512, respectively. A pair of _b_l_o_c_k_s_i_z_e_s can be separated + by x to indicate a product. A specific archive device may impose + additional restrictions on the size of blocking it will support. + When blocking is not specified, the default _b_l_o_c_k_s_i_z_e is dependent + on the specific archive format being used (see the --xx option). + + --cc Match all file or archive members _e_x_c_e_p_t those specified by the + _p_a_t_t_e_r_n and _f_i_l_e operands. + + --dd Cause files of type directory being copied or archived, or archive + members of type directory being extracted, to match only the direc- + tory file or archive member and not the file hierarchy rooted at + the directory. + + --ff _a_r_c_h_i_v_e + Specify _a_r_c_h_i_v_e as the pathname of the input or output archive, + overriding the default standard input (for _l_i_s_t and _r_e_a_d) or + standard output (for _w_r_i_t_e). A single archive may span multiple + files and different archive devices. When required, ppaaxx will + prompt for the pathname of the file or device of the next volume in + the archive. + + --ii Interactively rename files or archive members. For each archive + member matching a _p_a_t_t_e_r_n operand or each file matching a _f_i_l_e + operand, ppaaxx will prompt to _/_d_e_v_/_t_t_y giving the name of the file, + its file mode and its modification time. ppaaxx will then read a line + from _/_d_e_v_/_t_t_y. If this line is blank, the file or archive member + is skipped. If this line consists of a single period, the file or + archive member is processed with no modification to its name. Oth- + erwise, its name is replaced with the contents of the line. ppaaxx + will immediately exit with a non-zero exit status if <EOF> is en- + countered when reading a response or if _/_d_e_v_/_t_t_y cannot be opened + for reading and writing. + + --jj Use bzip2(1) for compression when reading or writing archive files. + + --kk Do not overwrite existing files. + + --ll Link files. (The letter ell). In the _c_o_p_y mode (--rr --ww), hard + links are made between the source and destination file hierarchies + whenever possible. + + --nn Select the first archive member that matches each _p_a_t_t_e_r_n operand. + No more than one archive member is matched for each _p_a_t_t_e_r_n.

In general, _o_p_t_i_o_n_s take the form: nnaammee==vvaalluuee + + --pp _s_t_r_i_n_g + Specify one or more file characteristic options (privileges). The + _s_t_r_i_n_g option-argument is a string specifying file characteristics + to be retained or discarded on extraction. The string consists of + the specification characters aa, ee, ff, mm, oo, and pp. Multiple char- + acteristics can be concatenated within the same string and multiple + --pp options can be specified. The meaning of the specification + characters are as follows: + + aa Do not preserve file access times. By default, file access + times are preserved whenever possible. + + ee `Preserve everything', the user ID, group ID, file mode bits, + file access time, and file modification time. This is intended + to be used by _r_o_o_t, someone with all the appropriate privi- + leges, in order to preserve all aspects of the files as they + are recorded in the archive. The ee flag is the sum of the oo + and pp flags. + + mm Do not preserve file modification times. By default, file mod- + ification times are preserved whenever possible. + + oo Preserve the user ID and group ID. + + pp `Preserve' the file mode bits. This is intended to be used by + a _u_s_e_r with regular privileges who wants to preserve all as- + pects of the file other than the ownership. The file times are + preserved by default, but two other flags are offered to dis- + able this and use the time of extraction instead. + + In the preceding list, `preserve' indicates that an attribute + stored in the archive is given to the extracted file, subject to + the permissions of the invoking process. Otherwise the attribute + of the extracted file is determined as part of the normal file cre- + ation action. If neither the ee nor the oo specification character + is specified, or the user ID and group ID are not preserved for any + reason, ppaaxx will not set the S_ISUID (_s_e_t_u_i_d) and S_ISGID (_s_e_t_g_i_d) + bits of the file mode. If the preservation of any of these items + fails for any reason, ppaaxx will write a diagnostic message to + standard error. Failure to preserve these items will affect the + final exit status, but will not cause the extracted file to be + deleted. If the file characteristic letters in any of the string + option-arguments are duplicated or conflict with each other, the + one(s) given last will take precedence. For example, if + --pp _e_m_e + is specified, file modification times are still preserved. + + --ss _r_e_p_l_s_t_r + Modify the file or archive member names specified by the _p_a_t_t_e_r_n or + _f_i_l_e operands according to the substitution expression _r_e_p_l_s_t_r, us- + ing the syntax of the ed(1) utility regular expressions. The for- + mat of these regular expressions are: + /old/new/[gp] + As in ed(1), oolldd is a basic regular expression and nneeww can contain + an ampersand (), \n (where n is a digit) back-references, or subex- + pression matching. The oolldd string may also contain <newline> char- + acters. Any non-null character can be used as a delimiter (/ is + shown here). Multiple --ss expressions can be specified. The ex- + pressions are applied in the order they are specified on the com- + mand line, terminating with the first successful substitution. The + optional trailing gg continues to apply the substitution expression + to the pathname substring which starts with the first character + following the end of the last successful substitution. The first + unsuccessful substitution stops the operation of the gg option. The + optional trailing pp will cause the final result of a successful + substitution to be written to standard error in the following for- + mat: + <original pathname> >> <new pathname> + File or archive member names that substitute to the empty string + are not selected and will be skipped. + + --tt Reset the access times of any file or directory read or accessed by + ppaaxx to be the same as they were before being read or accessed by , + if the user has the appropriate permissions required by utime(3). + + --uu Ignore files that are older (having a less recent file modification + time) than a pre-existing file or archive member with the same + name. During _r_e_a_d, an archive member with the same name as a file + in the file system will be extracted if the archive member is newer + than the file. During _w_r_i_t_e, a file system member with the same + name as an archive member will be written to the archive if it is + newer than the archive member. During _c_o_p_y, the file in the desti- + nation hierarchy is replaced by the file in the source hierarchy or + by a link to the file in the source hierarchy if the file in the + source hierarchy is newer. + + --vv During a _l_i_s_t operation, produce a verbose table of contents using + the format of the ls(1) utility with the --ll option. For pathnames + representing a hard link to a previous member of the archive, the + output has the format: + <ls -l listing> == <link name> + Where <ls -l listing> is the output format specified by the ls(1) + utility when used with the --ll option. Otherwise for all the other + operational modes (_r_e_a_d, _w_r_i_t_e, and _c_o_p_y), pathnames are written + and flushed to standard error without a trailing <newline> as soon + as processing begins on that file or archive member. The trailing + <newline>, is not buffered, and is written only after the file has + been read or written. + + --xx _f_o_r_m_a_t + Specify the output archive format, with the default format being + _u_s_t_a_r. ppaaxx currently supports the following formats: + + _c_p_i_o The extended cpio interchange format specified in the IEEE + Std 1003.2 (``POSIX.2'') standard.

Pathnames stored by this + format must be 250 characters or less in length. + + ppaaxx will detect and report any file that it is unable to store or + extract as the result of any specific archive format restrictions. + The individual archive formats may impose additional restrictions + on use. Typical archive format restrictions include (but are not + limited to): file pathname length, file size, link pathname length + and the type of the file. + + --zz Use gzip(1) compression, when reading or writing archive files. + + --AA Do not strip leading `/'s from file names. + + --BB _b_y_t_e_s + Limit the number of bytes written to a single archive volume to + _b_y_t_e_s. The _b_y_t_e_s limit can end with m, k, or b to specify multi- + plication by 1048576 (1M), 1024 (1K) or 512, respectively. A pair + of _b_y_t_e_s limits can be separated by x to indicate a product. + + _W_a_r_n_i_n_g: Only use this option when writing an archive to a device + which supports an end of file read condition based on last (or + largest) write offset (such as a regular file or a tape drive). + The use of this option with a floppy or hard disk is not recommend- + ed. + + --DD This option is the same as the --uu option, except that the file in- + ode change time is checked instead of the file modification time. + The file inode change time can be used to select files whose inode + information (e.g. uid, gid, etc.) is newer than a copy of the file + in the destination _d_i_r_e_c_t_o_r_y. + + --EE _l_i_m_i_t + Limit the number of consecutive read faults while trying to read a + flawed archives to _l_i_m_i_t. With a positive _l_i_m_i_t, ppaaxx will attempt + to recover from an archive read error and will continue processing + starting with the next file stored in the archive. A _l_i_m_i_t of 0 + will cause ppaaxx to stop operation after the first read error is de- + tected on an archive volume. A _l_i_m_i_t of NONE will cause ppaaxx to at- + tempt to recover from read errors forever. The default _l_i_m_i_t is a + small positive number of retries. + + _W_a_r_n_i_n_g: Using this option with NONE should be used with extreme + caution as ppaaxx may get stuck in an infinite loop on a very badly + flawed archive. + + --GG _g_r_o_u_p + Select a file based on its _g_r_o_u_p name, or when starting with a ##, a + numeric gid. A '\' can be used to escape the ##. Multiple --GG op- + tions may be supplied and checking stops with the first match. + + --HH Follow only command line symbolic links while performing a physical + file system traversal. + + --LL Follow all symbolic links to perform a logical file system traver- + sal. + + --MM During a _w_r_i_t_e or _c_o_p_y operation, treat the list of files on + standard input as an mtree(8) `specfile' specification, and write + or copy only those items in the specfile. + + If the file exists in the underlying file system, its permissions + and modification time will be used unless specifically overridden + by the specfile. An error will be raised if the type of entry in + the specfile conflicts with that of an existing file. A directory + entry that is marked `ooppttiioonnaall' will not be copied (even though its + contents will be). + + Otherwise, the entry will be `faked-up', and it is necessary to + specify at least the following parameters in the specfile: ttyyppee, + mmooddee, ggnnaammee or ggiidd, and uunnaammee or uuiidd, ddeevviiccee (in the case of block + or character devices), and lliinnkk (in the case of symbolic links). + If ttiimmee isn't provided, the current time will be used. A `faked- + up' entry that is marked `ooppttiioonnaall' will not be copied. + + --NN _d_b_d_i_r + Except for lookups for the --GG and --UU options, use the user database + text file _m_a_s_t_e_r_._p_a_s_s_w_d and group database text file _g_r_o_u_p from + _d_b_d_i_r, rather than using the results from the system's getpwnam(3) + and getgrnam(3) (and related) library calls. + + --OO Force the archive to be one volume. If a volume ends prematurely, + ppaaxx will not prompt for a new volume. This option can be useful + for automated tasks where error recovery cannot be performed by a + human. + + --PP Do not follow symbolic links, perform a physical file system + traversal. This is the default mode. + + --TT _[_f_r_o_m___d_a_t_e_]_[_,_t_o___d_a_t_e_]_[_/_[_c_]_[_m_]_] + Allow files to be selected based on a file modification or inode + change time falling within a specified time range of _f_r_o_m___d_a_t_e to + _t_o___d_a_t_e (the dates are inclusive). If only a _f_r_o_m___d_a_t_e is sup- + plied, all files with a modification or inode change time equal to + or younger are selected. If only a _t_o___d_a_t_e is supplied, all files + with a modification or inode change time equal to or older will be + selected. When the _f_r_o_m___d_a_t_e is equal to the _t_o___d_a_t_e, only files + with a modification or inode change time of exactly that time will + be selected. + + When ppaaxx is in the _w_r_i_t_e or _c_o_p_y mode, the optional trailing field + _[_c_]_[_m_] can be used to determine which file time (inode change, file + modification or both) are used in the comparison. If neither is + specified, the default is to use file modification time only. The + _m specifies the comparison of file modification time (the time when + the file was last written). The _c specifies the comparison of in- + ode change time (the time when the file inode was last changed; + e.g. a change of owner, group, mode, etc). When _c and _m are both + specified, then the modification and inode change times are both + compared. The inode change time comparison is useful in selecting + files whose attributes were recently changed or selecting files + which were recently created and had their modification time reset + to an older time (as what happens when a file is extracted from an + archive and the modification time is preserved). Time comparisons + using both file times is useful when ppaaxx is used to create a time + based incremental archive (only files that were changed during a + specified time range will be archived). + + A time range is made up of six different fields and each field must + contain two digits. The format is: + [[[[[cc]yy]mm]dd]hh]mm[.ss] + Where cccc is the first two digits of the year (the century), yyyy is + the last two digits of the year, the first mmmm is the month (from 01 + to 12), dddd is the day of the month (from 01 to 31), hhhh is the hour + of the day (from 00 to 23), the second mmmm is the minute (from 00 to + 59), and ssss is the seconds (from 00 to 61). Only the minute field + mmmm is required; the others will default to the current system val- + ues. The ssss field may be added independently of the other fields. + If the century is not specified, it defaults to 1900 for years be- + tween 69 and 99, or 2000 for years between 0 and 68. Time ranges + are relative to the current time, so + --TT _1_2_3_4_/_c_m + would select all files with a modification or inode change time of + 12:34 PM today or later. Multiple --TT time range can be supplied + and checking stops with the first match. + + --UU _u_s_e_r + Select a file based on its _u_s_e_r name, or when starting with a ##, a + numeric uid. A '\' can be used to escape the ##. Multiple --UU op- + tions may be supplied and checking stops with the first match. + + --XX When traversing the file hierarchy specified by a pathname, do not + descend into directories that have a different device ID. See the + st_dev field as described in stat(2) for more information about de- + vice ID's. + + --YY This option is the same as the --DD option, except that the inode + change time is checked using the pathname created after all the + file name modifications have completed. + + --ZZ This option is the same as the --uu option, except that the modifica- + tion time is checked using the pathname created after all the file + name modifications have completed. + + ----ffoorrccee--llooccaall + Do not interpret filenames that contain a `:' as remote files. + + ----iinnsseeccuurree + Normally ppaaxx ignores filenames that contain `..' as a path compo- + nent. With this option, files that contain `..' can be processed. + + The options that operate on the names of files or archive members (--cc, + --ii, --nn, --ss, --uu, --vv, --DD, --GG, --TT, --UU, --YY, and --ZZ) interact as follows. + + When extracting files during a _r_e_a_d operation, archive members are + `selected', based only on the user specified pattern operands as modified + by the --cc, --nn, --uu, --DD, --GG, --TT, --UU options. Then any --ss and --ii options + will modify in that order, the names of these selected files. Then the + --YY and --ZZ options will be applied based on the final pathname. Finally + the --vv option will write the names resulting from these modifications. + + When archiving files during a _w_r_i_t_e operation, or copying files during a + _c_o_p_y operation, archive members are `selected', based only on the user + specified pathnames as modified by the --nn, --uu, --DD, --GG, --TT, and --UU options + (the --DD option only applies during a copy operation). Then any --ss and --ii + options will modify in that order, the names of these selected files. + Then during a _c_o_p_y operation the --YY and the --ZZ options will be applied + based on the final pathname. Finally the --vv option will write the names + resulting from these modifications. + + When one or both of the --uu or --DD options are specified along with the --nn + option, a file is not considered selected unless it is newer than the + file to which it is compared. + +EEXXAAMMPPLLEESS + The command: + pax -w -f /dev/rst0 . + copies the contents of the current directory to the device _/_d_e_v_/_r_s_t_0. + + The command: + pax -v -f filename + gives the verbose table of contents for an archive stored in _f_i_l_e_n_a_m_e. + + The following commands: + mkdir newdir + cd olddir + pax -rw -pp . ../newdir + will copy the entire _o_l_d_d_i_r directory hierarchy to _n_e_w_d_i_r, preserving + permissions and access times. + + When running as root, one may also wish to preserve file ownership when + copying directory trees. This can be done with the following commands: + cd olddir + pax -rw -pe . .../newdir + which will copy the contents of _o_l_d_d_i_r into _._._._/_n_e_w_d_i_r, preserving owner- + ship, permissions and access times. + + The command: + pax -r -s ',^//*usr//*,,' -f a.pax + reads the archive _a_._p_a_x, with all files rooted in ``/usr'' into the + archive extracted relative to the current directory. + + The command: + pax -rw -i . dest_dir + can be used to interactively select the files to copy from the current + directory to _d_e_s_t___d_i_r. + + The command: + pax -r -pe -U root -G bin -f a.pax + will extract all files from the archive _a_._p_a_x which are owned by _r_o_o_t + with group _b_i_n and will preserve all file permissions. + + The command: + pax -r -w -v -Y -Z home /backup + will update (and list) only those files in the destination directory + _/_b_a_c_k_u_p which are older (less recent inode change or file modification + times) than files with the same name found in the source file tree _h_o_m_e. + +EERRRROORRSS + ppaaxx will exit with one of the following values: + + 0 All files were processed successfully. + + 1 An error occurred. + + Whenever ppaaxx cannot create a file or a link when reading an archive or + cannot find a file when writing an archive, or cannot preserve the user + ID, group ID, or file mode when the --pp option is specified, a diagnostic + message is written to standard error and a non-zero exit status will be + returned, but processing will continue. In the case where pax cannot + create a link to a file, ppaaxx will not create a second copy of the file. + + If the extraction of a file from an archive is prematurely terminated by + a signal or error, ppaaxx may have only partially extracted a file the user + wanted. Additionally, the file modes of extracted files and directories + may have incorrect file bits, and the modification and access times may + be wrong. + + If the creation of an archive is prematurely terminated by a signal or + error, ppaaxx may have only partially created the archive which may violate + the specific archive format specification. + + If while doing a _c_o_p_y, ppaaxx detects a file is about to overwrite itself, + the file is not copied, a diagnostic message is written to standard error + and when ppaaxx completes it will exit with a non-zero exit status. + +SSEEEE AALLSSOO + cpio(1), tar(1), symlink(7), mtree(8) + +SSTTAANNDDAARRDDSS + The ppaaxx utility is a superset of the IEEE Std 1003.2 (``POSIX.2'') stan- + dard.
