+.Sh NAME
+.Nm chown
+.Nd change file owner and group
+.Sh SYNOPSIS
+.Nm chown
+.Op Fl Rf
+.Op Ar owner
+.Op Ar group
+.Ar file ...
+.Sh DESCRIPTION
+.Nm Chown
+sets the user ID and/or the group ID of the specified files.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl R
+Change the user ID and/or the group ID for the file hierarchies rooted
+in the files instead of just the files themselves.
+.It Fl f
+Don't report any failure to change file owner or group, nor modify
+the exit status to reflect such failures.
+.El
+.Pp
+The
+.Ar owner
+and
+.Ar group
+operands are both optional, but at least one must be specified; if
+the group operand is specified, it must be preceded by a colon (``:'')
+character.
+.Pp
+The
+.Ar owner
+may be either a numeric user ID or a user name.
+If a user name is also a numeric user ID, the operand is used as a
+user name.
+The
+.Ar group
+may be either a numeric group ID or a group name.
+If a group name is also a numeric group ID, the operand is used as a
+group name.
+.Pp
+The ownership of a file may only be altered by a super-user for
+obvious security reasons.
+.Pp
+The owner and group of symbolic links are themselves changed instead
+of the file to which the link points.
+.Pp
+The
+.Nm chown
+utility exits 0 on success, and >0 if an error occurs.
+.Sh COMPATIBILITY
+Previous versions of the
+.Nm chown
+utility used the dot (``.'') character to distinguish the group name.
+This has been changed to be a colon (``:'') character so that user and
+group names may contain the dot character.
+.Sh SEE ALSO
+.Xr chgrp 1 ,
+.Xr find 1 ,
+.Xr chown 2
+.Sh STANDARDS
+The
+.Nm chown
+command is expected to be POSIX 1003.2 compliant.
