+\fBchmod\fP [\fIOPTION\fP]... \fIMODE\fP[\fI,MODE\fP]... \fIFILE\fP...
+.br
+\fBchmod\fP [\fIOPTION\fP]... \fIOCTAL\-MODE FILE\fP...

+\fBchmod\fP [\fIOPTION\fP]... \fI\-\-reference=RFILE FILE\fP...
+.SH 説明
+This manual page documents the GNU version of \fBchmod\fP. \fBchmod\fP changes
+the file mode bits of each given file according to \fImode\fP, which can be
+either a symbolic representation of changes to make, or an octal number
+representing the bit pattern for the new mode bits.
+.PP
+The format of a symbolic mode is
+[\fBugoa\fP.\|.\|.][[\fB+\-=\fP][\fIperms\fP.\|.\|.].\|.\|.], where \fIperms\fP is either
+zero or more letters from the set \fBrwxXst\fP, or a single letter from the set
+\fBugo\fP. Multiple symbolic modes can be given, separated by commas.
+.PP
+A combination of the letters \fBugoa\fP controls which users' access to the
+file will be changed: the user who owns it (\fBu\fP), other users in the file's
+group (\fBg\fP), other users not in the file's group (\fBo\fP), or all users
+(\fBa\fP). If none of these are given, the effect is as if \fBa\fP were given,
+but bits that are set in the umask are not affected.
+.PP
+The operator \fB+\fP causes the selected file mode bits to be added to the
+existing file mode bits of each file; \fB\-\fP causes them to be removed; and
+\fB=\fP causes them to be added and causes unmentioned bits to be removed
+except that a directory's unmentioned set user and group ID bits are not
+affected.
+.PP
+The letters \fBrwxXst\fP select file mode bits for the affected users: read
+(\fBr\fP), write (\fBw\fP), execute (or search for directories) (\fBx\fP),
+execute/search only if the file is a directory or already has execute
+permission for some user (\fBX\fP), set user or group ID on execution (\fBs\fP),
+restricted deletion flag or sticky bit (\fBt\fP). Instead of one or more of
+these letters, you can specify exactly one of the letters \fBugo\fP: the
+permissions granted to the user who owns the file (\fBu\fP), the permissions
+granted to other users who are members of the file's group (\fBg\fP), and the
+permissions granted to users that are in neither of the two preceding
+categories (\fBo\fP).
+.PP
+A numeric mode is from one to four octal digits (0\-7), derived by adding up
+the bits with values 4, 2, and 1. Omitted digits are assumed to be leading
+zeros. The first digit selects the set user ID (4) and set group ID (2) and
+restricted deletion or sticky (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.
+.PP
+\fBchmod\fP never changes the permissions of symbolic links; the \fBchmod\fP
+system call cannot change their permissions. This is not a problem since
+the permissions of symbolic links are never used. However, for each
+symbolic link listed on the command line, \fBchmod\fP changes the permissions
+of the pointed\-to file. In contrast, \fBchmod\fP ignores symbolic links
+encountered during recursive directory traversals.
+.SH "SETUID AND SETGID BITS"
+\fBchmod\fP clears the set\-group\-ID bit of a regular file if the file's group
+ID does not match the user's effective group ID or one of the user's
+supplementary group IDs, unless the user has appropriate privileges.
+Additional restrictions may cause the set\-user\-ID and set\-group\-ID bits of
+\fIMODE\fP or \fIRFILE\fP to be ignored. This behavior depends on the policy and
+functionality of the underlying \fBchmod\fP system call. When in doubt, check
+the underlying system behavior.
+.PP
+\fBchmod\fP preserves a directory's set\-user\-ID and set\-group\-ID bits unless
+you explicitly specify otherwise. You can set or clear the bits with
+symbolic modes like \fBu+s\fP and \fBg\-s\fP, and you can set (but not clear) the
+bits with a numeric mode.
+.SH "RESTRICTED DELETION FLAG OR STICKY BIT"
+The restricted deletion flag or sticky bit is a single bit, whose
+interpretation depends on the file type. For directories, it prevents
+unprivileged users from removing or renaming a file in the directory unless
+they own the file or the directory; this is called the \fIrestricted deletion
+flag\fP for the directory, and is commonly found on world\-writable directories
+like \fB/tmp\fP. For regular files on some older systems, the bit saves the
+program's text image on the swap device so it will load more quickly when
+run; this is called the \fIsticky bit\fP.
+.SH オプション
