The selected + programs can still be called directly using symlinks to "coreutils" or + shebangs with the option --coreutils-prog= passed to this program. The + install behavior is determined by the option --enable-single-binary=symlinks + or --enable-single-binary=shebangs (the default). With the symlinks option, + you can't make a second symlink to any program because that will change the + name of the called program, which is used by coreutils to determine the + desired program. The shebangs option doesn't suffer from this problem, but + the /proc/$pid/cmdline file might not be updated on all the platforms. The + functionality of each program is not affected but this single binary will + depend on all the required dynamic libraries even to run simple programs. + If you desire to build some tools outside the single binary file, you can + pass the option --enable-single-binary-exceptions=PROG_LIST with the comma + separated list of programs you want to build separately. This flag + considerably reduces the overall size of the installed binaries which makes + it suitable for embedded system. + +** Changes in behavior + + chroot with an argument of "/" no longer implicitly changes the current + directory to "/", allowing changing only user credentials for a command. + + chroot --userspec will now unset supplemental groups associated with root, + and instead use the supplemental groups of the specified user. + + cut -d$'\n' again outputs lines identified in the --fields list, having + not done so in v8.21 and v8.22. Note using this non portable functionality + will result in the delayed output of lines. + + ls with none of LS_COLORS or COLORTERM environment variables set, + will now honor an empty or unknown TERM environment variable, + and not output colors even with --colors=always. + +** Improvements + + chroot has better --userspec and --group look-ups, with numeric IDs never + causing name look-up errors. Also look-ups are first done outside the chroot, + in case the look-up within the chroot fails due to library conflicts etc. + + install now allows the combination of the -D and -t options. + + numfmt supports zero padding of numbers using the standard printf + syntax of a leading zero, for example --format="%010f". + Also throughput was improved by up to 800% by avoiding redundant processing. + + shred now supports multiple passes on GNU/Linux tape devices by rewinding + the tape before each pass, avoids redundant writes to empty files, + uses direct I/O for all passes where possible, and attempts to clear + inode storage used for small files on some file systems. + + split avoids unnecessary input buffering, immediately writing input to output + which is significant with --filter or when writing to fifos or stdout etc. + + stat and tail work better with HFS+, HFSX, LogFS and ConfigFS. stat -f + --format=%T now reports the file system type, and tail -f now uses inotify, + rather than the default of issuing a warning and reverting to polling. + + +* Noteworthy changes in release 8.22 (2013-12-13) [stable] + +** Bug fixes + + df now processes the mount list correctly in the presence of unstatable + mount points.

As with the sort,uniq + option of the same name, this makes join consume and produce NUL-terminated + lines rather than newline-terminated lines. + + uniq accepts a new option: --group to print all items, while separating + unique groups with empty lines. + + shred accepts new parameters to the --remove option to give greater + control over that operation, which can greatly reduce sync overhead. + + shuf accepts a new option: --repeat (-r), which can repeat items in + the output. + +** Changes in behavior + + cp --link now dereferences a symbolic link as source before creating the + hard link in the destination unless the -P,--no-deref option is specified. + Previously, it would create a hard link of the symbolic link, even when + the dereferencing options -L or -H were specified. + + cp, install, mkdir, mknod and mkfifo no longer accept an argument to the + short -Z option. The --context equivalent still takes an optional argument. + + dd status=none now suppresses all non fatal diagnostic messages, + not just the transfer counts. + + df no longer accepts the long-obsolescent --megabytes option. + + stdbuf now requires at least one buffering mode option to be specified, + as per the documented interface. + +** Improvements + + base64 encoding throughput for bulk data is increased by about 60%. + + md5sum can use libcrypto hash routines where allowed to potentially + get better performance through using more system specific logic. + sha1sum for example has improved throughput by 40% on an i3-2310M. + This also affects sha1sum, sha224sum, sha256sum, sha384sum and sha512sum. + + stat and tail work better with EFIVARFS, EXOFS, F2FS, HOSTFS, SMACKFS, SNFS + and UBIFS. stat -f --format=%T now reports the file system type, and tail -f + now uses inotify for files on all those except SNFS, rather than the default + (for unknown file system types) of issuing a warning and reverting to polling. + + shuf outputs subsets of large inputs much more efficiently. + Reservoir sampling is used to limit memory usage based on the number of + outputs, rather than the number of inputs. + + shred increases the default write block size from 12KiB to 64KiB + to align with other utilities and reduce the system call overhead. + + split --line-bytes=SIZE, now only allocates memory as needed rather + than allocating SIZE bytes at program start. + + stty now supports configuring "stick" (mark/space) parity where available. + +** Build-related + + factor now builds on aarch64 based systems [bug introduced in coreutils-8.20] + + * Noteworthy changes in release 8.21 (2013-02-14) [stable] ** New programs @@ -16,6 +333,9 @@ GNU coreutils NEWS -*- outline -*- with such a minimum SIZE (or a maximum SIZE if it is negative). du recognizes -t SIZE as equivalent, for compatibility with FreeBSD. + timeout now accepts the --preserve-status option to always propagate the exit + status, useful for commands that can run for an indeterminite amount of time. + ** Bug fixes cp --no-preserve=mode now no longer exits non-zero. @@ -79,6 +399,9 @@ GNU coreutils NEWS -*- outline -*- the system by skipping duplicate entries (identified by the device number).
