CHGRP(1)                     BSD Reference Manual                     CHGRP(1)

NAME
     chgrp - change group

SYNOPSIS
     chgrp [-Rf] group files ...

DESCRIPTION
     The chgrp utility sets the group ID of the file named by each file
     operand to the group ID specified by the group operand.

     Options:

     -R      Recursively change file group IDs.  For each file operand that
             names a directory, chgrp changes the group of the directory and
             all files in the file hierarchy below it.  When symbolic links
             are encountered, their group is changed, but they are not tra-
             versed.

     -f      The force option ignores errors, except for usage errors and
             doesn't query about strange modes (unless user does not have
             proper permissions).

     Operands:

     group  The group can be either a group name from the group database, or a
            numeric group ID.

     file   A pathname of a file whose group ID is to be modified.

     The user invoking must belong to the specified group and be the owner of
     the file, or be the super-user.

     The chgrp utility exits 0 on success, and >0 if an error occurs.

FILES
     /etc/group  Group ID file

STANDARDS
     The chgrp function is expected to be POSIX 1003.2 compatible.  This manu-
     al page is derived from the POSIX 1003.2 manual page.
