-"[+NAME?chmod - change the access permissions of files]"
-"[+DESCRIPTION?\bchmod\b changes the permission of each file "
- "according to mode, which can be either a symbolic representation "
- "of changes to make, or an octal number representing the bit "
- "pattern for the new permissions.]"
-"[+?Symbolic mode strings consist of one or more comma separated list "
- "of operations that can be perfomed on the mode. Each operation is of "
- "the form \auser\a \aop\a \aperm\a where \auser\a is zero or more of "
- "the following letters:]{"
- "[+u?User permission bits.]"
- "[+g?Group permission bits.]"
- "[+o?Other permission bits.]"
- "[+a?All permission bits. This is the default if none are specified.]"
- "}"
-"[+?The \aperm\a portion consists of zero or more of the following letters:]{"
- "[+r?Read permission.]"
- "[+s?Setuid when \bu\b is selected for \awho\a and setgid when \bg\b "
- "is selected for \awho\a.]"
- "[+w?Write permission.]"
- "[+x?Execute permission for files, search permission for directories.]"
- "[+X?Same as \bx\b except that it is ignored for files that do not "
- "already have at least one \bx\b bit set.]"
- "[+l?Exclusive lock bit on systems that support it. Group execute "
- "must be off.]"
- "[+t?Sticky bit on systems that support it.]"
- "}"
-"[+?The \aop\a portion consists of one or more of the following characters:]{"
- "[++?Cause the permission selected to be added to the existing "
- "permissions. | is equivalent to +.]"
- "[+-?Cause the permission selected to be removed to the existing "
- "permissions.]"
- "[+=?Cause the permission to be set to the given permissions.]"
- "[+&?Cause the permission selected to be \aand\aed with the existing "
- "permissions.]"
- "[+^?Cause the permission selected to be propagated to more "
- "restrictive groups.]"
- "}"
-"[+?Symbolic modes with the \auser\a portion omitted are subject to "
- "\bumask\b(2) settings unless the \b=\b \aop\a or the "
- "\b--ignore-umask\b option is specified.]"
-"[+?A numeric mode is from one to four octal digits (0-7), "
- "derived by adding up the bits with values 4, 2, and 1. "
- "Any omitted digits are assumed to be leading zeros. The "
- "first digit selects the set user ID (4) and set group ID "
- "(2) and save text image (1) attributes. The second digit "
- "selects permissions for the user who owns the file: read "
- "(4), write (2), and execute (1); the third selects permissions"
- "for other users in the file's group, with the same values; "
- "and the fourth for other users not in the file's group, with "
- "the same values.]"
-
-"[+?For symbolic links, by default, \bchmod\b changes the mode on the file "
- "referenced by the symbolic link, not on the symbolic link itself. "
- "The \b-h\b options can be specified to change the mode of the link. "
- "When traversing directories with \b-R\b, \bchmod\b either follows "
- "symbolic links or does not follow symbolic links, based on the "
- "options \b-H\b, \b-L\b, and \b-P\b. The configuration parameter "
- "\bPATH_RESOLVE\b determines the default behavior if none of these "
- "options is specified.]"
-
-"[+?When the \b-c\b or \b-v\b options are specified, change notifications "
- "are written to standard output using the format, "
- "\b%s: mode changed to %0.4o (%s)\b, with arguments of the "
- "pathname, the numeric mode, and the resulting permission bits as "
- "would be displayed by the \bls\b command.]"
-
-"[+?For backwards compatibility, if an invalid option is given that is a valid "
- "symbolic mode specification, \bchmod\b treats this as a mode "
- "specification rather than as an option specification.]"
-
-"[H:metaphysical?Follow symbolic links for command arguments; otherwise don't "
- "follow symbolic links when traversing directories.]"
-"[L:logical|follow?Follow symbolic links when traversing directories.]"
-"[P:physical|nofollow?Don't follow symbolic links when traversing directories.]"
-"[R:recursive?Change the mode for files in subdirectories recursively.]"
-"[c:changes?Describe only files whose permission actually change.]"
-"[f:quiet|silent?Do not report files whose permissioins fail to change.]"
-"[h:symlink?Change the mode of the symbolic links on systems that "
- "support this.]"
-"[i:ignore-umask?Ignore the \bumask\b(2) value in symbolic mode "
- "expressions. This is probably how you expect \bchmod\b to work.]"
-"[n:show?Show actions but do not change any file modes.]"
-"[F:reference?Omit the \amode\a operand and use the mode of \afile\a "
- "instead.]:[file]"
-"[v:verbose?Describe changed permissions of all files.]"
-"\n"
-"\nmode file ...\n"
-"\n"
-"[+EXIT STATUS?]{"
- "[+0?All files changed successfully.]"
- "[+>0?Unable to change mode of one or more files.]"
