CHGRP(1)            RISC/os Reference Manual             CHGRP(1)



NAME
     chgrp - change the group ownership of a file

SYNOPSIS
     chgrp [-h] [-R] 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 the super-user to use
     this command.

     The operating system has a configuration option
     {_POSIX_CHOWN_RESTRICTED}, 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 the following options:

     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.

     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.

FILES
     /etc/group

NOTES
     In a Remote File Sharing environment, you may not have the
     permissions that the output of the ls -l command leads you
     to believe.
