chgrp(1)                 USER COMMANDS                   chgrp(1)



NAME
     chgrp - change the group ownership of a file

SYNOPSIS
     chgrp [-R] [-h] group file ...

DESCRIPTION
     chgrp changes the group ID of the files given  as  arguments
     to  group.   The group may be either a decimal group ID or a
     group name found in the group ID file, /etc/group.  You must
     be  the  owner of the file, or be the super-user to use this
     command.  The operating system has  a  configuration  option
     {POSIXCHOWNRESTRICTED},  to  restrict  ownership changes.
     When this option is in effect, the owner  of  the  file  may
     change  the  group  of the file only to a group to which the
     owner belongs.  Only the super-user can  arbitrarily  change
     owner  IDs  whether  this option is in effect or not.  chgrp
     has one option:

     -R   Recursive.  chgrp descends through the  directory,  and
          any  subdirectories,  setting the specified group ID as
          it proceeds.  When symbolic links are encountered, they
          are traversed.

     -h   If the file is a symbolic link, change the group of the
          symbolic  link.   Without this option, the group of the
          file referenced by the symbolic link is changed.

FILES
     /etc/group

     In a Remote File Sharing environment, you may not  have  the
     permissions  that  the output of the ls -l command leads you
     to believe.  For more information see the Network User's and
