Fl L | Fl P +.Oc +.Op Fl fh +.Fl Fl reference=rfile +.Ar +.Sh DESCRIPTION +The +.Nm +utility modifies the file mode bits of the listed files +as specified by the +.Ar mode +operand, or +copied from a reference +.Ar rfile , +as specified with the +.Fl Fl reference +argument. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl H +If the +.Fl R +option is specified, symbolic links on the command line are followed. +(Symbolic links encountered in the tree traversal are not followed.) +.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. +.It Fl R +Change the modes of the file hierarchies rooted in the files +instead of just the files themselves. +.It Fl f +Do not display a diagnostic message or modify the exit status if +.Nm +fails to change the mode of a file. +.It Fl h +If +.Ar file +is symbolic link, the mode of the link is changed. +.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 +Only the owner of a file or the super-user is permitted to change +the mode of a file. +.Sh EXIT STATUS +The +.Nm +utility exits 0 on success, and \*[Gt]0 if an error occurs. +.Sh MODES +Modes may be absolute or symbolic. +An absolute mode is an octal number constructed by +.Em or Ap ing +the following values: +.Pp +.Bl -tag -width 6n -compact -offset indent +.It Li 4000 +set-user-ID-on-execution +.It Li 2000 +set-group-ID-on-execution +.It Li 1000 +sticky bit, see +.Xr chmod 2 +.It Li 0400 +read by owner +.It Li 0200 +write by owner +.It Li 0100 +execute (or search for directories) by owner +.It Li 0070 +read, write, execute/search by group +.It Li 0007 +read, write, execute/search by others +.El +.Pp +The read, write, and execute/search values for group and others +are encoded as described for owner. +.Pp +The symbolic mode is described by the following grammar: +.Bd -literal -offset indent +mode ::= clause [, clause ...] +clause ::= [who ...] [action ...] last_action +action ::= op [perm ...] +last_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 mode of the original file. +.It g +The group permission bits in the mode of the original file. +.It o +The other permission bits in the mode of the original 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 +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 clear, 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 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. +.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

+.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

Absolute modes are given as an -octal number that represents the new file mode. The mode bits are defined as -follows: -.ta 0.25i -.nf -.PP - 4000 Set effective user id on execution to file's owner id - 2000 Set effective group id on execution to file's group id - 0400 file is readable by the owner of the file - 0200 writeable by owner - 0100 executable by owner - 0070 same as above, for other users in the same group - 0007 same as above, for all other users -.PP -.fi -Symbolic modes modify the current file mode in a specified way. The form is: -.PP - [who] op permissions { op permissions ...} {, [who] op ... } -.PP -The possibilities for \fIwho\fR are \fIu\fR, \fIg\fR, \fIo\fR, and \fIa\fR, -standing for user, group, other and all, respectively. -If \fIwho\fR is omitted, \fIa\fR is assumed, but the current umask is used. -The op can be \fI+\fR, \fI-\fR, or \fI=\fR; \fI+\fR turns on the -given permissions, \fI\- \fRturns them off; \fI=\fR sets the permissions -exclusively for the given \fIwho\fR. -For example \fIg=x\fR sets the group permissions to \fI--x\fR. -.PP -The possible permissions are \fIr\fR, \fIw\fR, \fIx\fR; which stand for read, -write, and execute; \fIs\fR turns on the set effective user/group id bits. -\fIs\fR only makes sense with \fIu\fR and \fIg\fR;\fR o+s\fR is -harmless. -.SH "SEE ALSO" -.BR ls (1), -.BR chmod (2). -- 2.44.0
