+The

+utility sets the group ID of the file named by each
+.Ar file
+operand to the
+.Ar group
+ID specified by the group operand.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl f
+The force option ignores errors, except for usage errors and doesn't
+query about strange modes (unless the user does not have proper permissions).
+.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 h
+If the file is a symbolic link, the group ID of the link itself is changed
+rather than the file that is pointed 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. Use
+.Fl h
+to change the group ID of a symbolic link.
+.It Fl R
+Change the group ID for the file hierarchies rooted
+in the files instead of just the files themselves.
+.It Fl n
+Interpret the group ID as numeric, avoiding the name lookup.
+.It Fl v
+Cause
+.Nm chgrp
+to be verbose, showing files as the group is modified.

+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
+The
+.Ar group
+operand can be either a group name from the group database,
+or a numeric group ID.
+If a group name is also a numeric group ID, the operand is used as a
+group name.
+.Pp
+The user invoking
+.Nm chgrp
+must belong to the specified group and be the owner of the file,

+.Sh DIAGNOSTICS

+.Sh DESCRIPTION
+The
+.Nm chown
+utility changes the user ID and/or the group ID of the specified files.
+Symbolic links named by arguments are silently left unchanged unless
+.Fl h
+is used.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl f
+Don't report any failure to change file owner or group, 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.
+(Symbolic links encountered in the tree traversal are not followed.)
+.It Fl h
+If the file is a symbolic link, change the user ID and/or the
+group ID of the link itself.
+.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.
+Instead, the user and/or group ID of the link itself are modified.
+This is the default. Use
+.Fl h
+to change the user ID and/or the group of symbolic links.
+.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 n
+Interpret user ID and group ID as numeric, avoiding name lookups.
+.It Fl v
+Cause
+.Nm chown
+to be verbose, showing files as the owner is modified.
+.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
+The
+.Ar owner
+and
+.Ar group
+operands are both optional;
+however, at least one must be specified.
+If the
+.Ar 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
+For obvious security reasons,
+the ownership of a file may only be altered by a super-user.
+Similarly, only a member of a group can change a file's group ID
+to that group.
+.Sh DIAGNOSTICS
+.Ex -std
+.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.
+.Pp
+On previous versions of this system,
+symbolic links did not have owners.
+.Pp
+The
+.Fl v
+option is non-standard and its use in scripts is not recommended.
+.Sh LEGACY DESCRIPTION
+In legacy mode, the
+.Fl R
+and
+.Fl RP
+options do not change the user ID
+or the group ID of symbolic links.
+.Sh SEE ALSO
+.Xr chgrp 1 ,
+.Xr find 1 ,
+.Xr chown 2 ,
+.Xr fts 3 ,
+.Xr compat 5 ,

+.Sh STANDARDS
+The
+.Nm chown
+utility is expected to be
+.St -p1003.2
+compliant.

+utility appeared in
