+.Nd change file modes
+.Sh SYNOPSIS
+.Nm
+.Oo
+.Fl R
+.Op Fl H | Fl L | Fl P
+.Oc
+.Op Fl fh
+.Ar mode
+.Ar
+.Nm
+.Oo
+.Fl R
+.Op Fl H | 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
+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.

+.Sh STANDARDS
+The
+.Nm
+utility is expected to be
+.St -p1003.2-92
+compatible with the exception of the
+.Ar perm
+symbol
+.Dq t
+which is not included in that standard.
+.Sh BUGS
+There's no
+.Ar perm
+option for the naughty bits.

-.SH DESCRIPTION
-.PP
-The given mode is applied to each file in the file list. If the \fB\-R\fR
-flag is present, the files in a directory will be changed as well.
-The mode can be either absolute or symbolic. 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.
