NAME +.Nm chmod +.Nd change file modes +.Sh SYNOPSIS +.Nm +.Op Fl fhv +.Op Fl R Op Fl H | L | P +.Ar mode +.Ar +.Sh DESCRIPTION +The +.Nm +utility modifies the file mode bits of the listed files +as specified by the +.Ar mode +operand. +.Pp +The options are as follows: +.Bl -tag -width indent +.It Fl f +Do not display a diagnostic message if +.Nm +could not modify the mode for +.Va file , +nor modify the exit status to reflect such failures. +.It Fl H +If the +.Fl R +option is specified, symbolic links on the command line are followed +and hence unaffected by the command. +(Symbolic links encountered during tree traversal are not followed.) +.It Fl h +If the file is a symbolic link, change the mode of the link itself +rather than the file that the link points to. +.It Fl L +If the +.Fl R +option is specified, all symbolic links are followed. +.It Fl P +If the +.Fl R +option is specified, no symbolic links are followed. +This is the default. +.It Fl R +Change the modes of the file hierarchies rooted in the files, +instead of just the files themselves. +Beware of unintentionally matching the +.Dq Pa ".." +hard link to the parent directory when using wildcards like +.Dq Li ".*" . +.It Fl v +Cause +.Nm +to be verbose, showing filenames as the mode is modified. +If the +.Fl v +flag is specified more than once, the old and new modes of the file +will also be printed, in both octal and symbolic notation. +.El +.Pp +The +.Fl H , +.Fl L +and +.Fl P +options are ignored unless the +.Fl R +option is specified. +In addition, these options override each other and the +command's actions are determined by the last one specified. +.Pp +If +.Nm +receives a +.Dv SIGINFO +signal (see the +.Cm status +argument for +.Xr stty 1 ) , +then the current filename as well as the old and new modes are displayed. +.Pp +Only the owner of a file or the super-user is permitted to change +the mode of a file. +.Sh EXIT STATUS +.Ex -std +.Sh MODES +Modes may be absolute or symbolic. +An absolute mode is an octal number constructed from the sum of +one or more of the following values: +.Pp +.Bl -tag -width 6n -compact -offset indent +.It Li 4000 +(the setuid bit). +Executable files with this bit set +will run with effective uid set to the uid of the file owner. +Directories with this bit set will force all files and +sub-directories created in them to be owned by the directory owner +and not by the uid of the creating process, if the underlying file +system supports this feature: see +.Xr chmod 2 +and the +.Cm suiddir +option to +.Xr mount 8 . +.It Li 2000 +(the setgid bit). +Executable files with this bit set +will run with effective gid set to the gid of the file owner. +.It Li 1000 +(the sticky bit). +See +.Xr chmod 2 +and +.Xr sticky 7 . +.It Li 0400 +Allow read by owner. +.It Li 0200 +Allow write by owner. +.It Li 0100 +For files, allow execution by owner. +For directories, allow the owner to +search in the directory. +.It Li 0040 +Allow read by group members. +.It Li 0020 +Allow write by group members. +.It Li 0010 +For files, allow execution by group members. +For directories, allow +group members to search in the directory. +.It Li 0004 +Allow read by others. +.It Li 0002 +Allow write by others. +.It Li 0001 +For files, allow execution by others. +For directories allow others to +search in the directory. +.El +.Pp +For example, the absolute mode that permits read, write and execute by +the owner, read and execute by group members, read and execute by +others, and no set-uid or set-gid behaviour is 755 +(400+200+100+040+010+004+001). +.Pp +The symbolic mode is described by the following grammar: +.Bd -literal -offset indent +mode ::= clause [, clause ...] +clause ::= [who ...] [action ...] action +action ::= op [perm ...] +who ::= a | u | g | o +op ::= + | \- | = +perm ::= r | s | t | w | x | X | u | g | o +.Ed +.Pp +The +.Ar who +symbols ``u'', ``g'', and ``o'' specify the user, group, and other parts +of the mode bits, respectively. +The +.Ar who +symbol ``a'' is equivalent to ``ugo''. +.Pp +The +.Ar perm +symbols represent the portions of the mode bits as follows: +.Pp +.Bl -tag -width Ds -compact -offset indent +.It r +The read bits. +.It s +The set-user-ID-on-execution and set-group-ID-on-execution bits. +.It t +The sticky bit. +.It w +The write bits. +.It x +The execute/search bits. +.It X +The execute/search bits if the file is a directory or any of the +execute/search bits are set in the original (unmodified) mode. +Operations with the +.Ar perm +symbol ``X'' are only meaningful in conjunction with the +.Ar op +symbol ``+'', and are ignored in all other cases. +.It u +The user permission bits in the original mode of the file. +.It g +The group permission bits in the original mode of the file. +.It o +The other permission bits in the original mode of the file. +.El +.Pp +The +.Ar op +symbols represent the operation performed, as follows: +.Bl -tag -width 4n +.It + +If no value is supplied for +.Ar perm , +the ``+'' operation has no effect. +If no value is supplied for +.Ar who , +each permission bit specified in +.Ar perm , +for which the corresponding bit in the file mode creation mask +(see +.Xr umask 2 ) +is clear, is set. +Otherwise, the mode bits represented by the specified +.Ar who +and +.Ar perm +values are set. +.It \&\- +If no value is supplied for +.Ar perm , +the ``\-'' operation has no effect. +If no value is supplied for +.Ar who , +each permission bit specified in +.Ar perm , +for which the corresponding bit in the file mode creation mask +is set, is cleared. +Otherwise, the mode bits represented by the specified +.Ar who +and +.Ar perm +values are cleared. +.It = +The mode bits specified by the +.Ar who +value are cleared, or, if no +.Ar who +value is specified, the owner, group +and other mode bits are cleared. +Then, if no value is supplied for +.Ar who , +each permission bit specified in +.Ar perm , +for which the corresponding bit in the file mode creation mask +is clear, is set. +Otherwise, the mode bits represented by the specified +.Ar who +and +.Ar perm +values are set. +.El +.Pp +Each +.Ar clause +specifies one or more operations to be performed on the mode +bits, and each operation is applied to the mode bits in the +order specified. +.Pp +Operations upon the other permissions only (specified by the symbol +``o'' by itself), in combination with the +.Ar perm +symbols ``s'' or ``t'', are ignored. +.Pp +The ``w'' permission on directories will permit file creation, relocation, +and copy into that directory. +Files created within the directory itself will inherit its group ID. +.Sh EXAMPLES +.Bl -tag -width "u=rwx,go=u-w" -compact +.It Li 644 +make a file readable by anyone and writable by the owner only. +.Pp +.It Li go-w +deny write permission to group and others. +.Pp +.It Li =rw,+X +set the read and write permissions to the usual defaults, but +retain any execute permissions that are currently set. +.Pp +.It Li +X +make a directory or file searchable/executable by everyone if it is +already searchable/executable by anyone. +.Pp +.It Li 755 +.It Li u=rwx,go=rx +.It Li u=rwx,go=u-w +make a file readable/executable by everyone and writable by the owner only. +.Pp +.It Li go= +clear all mode bits for group and others. +.Pp +.It Li g=u-w +set the group bits equal to the user bits, but clear the group write bit. +.El +.Sh COMPATIBILITY +The +.Fl v +option is non-standard and its use in scripts is not recommended. +.Sh SEE ALSO +.Xr chflags 1 , +.Xr install 1 , +.Xr setfacl 1 , +.Xr chmod 2 ,

with the exception of the +.Ar perm +symbol +.Dq t +which is not included in that standard. +.Sh HISTORY +A +.Nm +command appeared in +.At v1 . +.Sh BUGS +There is no +.Ar perm +option for the naughty
