SYNOPSIS

       chgrp [options] group file...

       POSIX options: [-R] [--]

       Austin draft options: [-hHLPR]

       GNU  options (shortest form): [-cfvR] [--help] [--version]

DESCRIPTION

       chgrp changes the group ownership of each  given  file  to
       group, which can be either a group name or a numeric group
       ID.

POSIX OPTIONS

       -R     Recursively change the group ownership of  directo-
              ries  and  their contents.  (And continue even when
              errors are encountered.)

       --     Terminate option list.

AUSTIN DRAFT OPTIONS

       -h     For each file operand  given  that  is  a  symlink,
              change  the  group ownership of the symlink itself,
              rather than the object it points to. If the  system
              does not support a group ownership for symlinks, do
              nothing for a symlink.

       -H (half-logical)
              (When given  together  with  -R.)   For  each  file
              operand  given  that  is  a symlink to a directory,
              change the group ownership of the directory and all
              files in the file hierarchy below it.

       -L (logical)
              (When  given  together  with  -R.)   For each file,
              either command line operand or  encountered  during
              the  tree  walk,  that is a symlink to a directory,
              change the group ownership of the directory and all
              files in the file hierarchy below it.

       -P (physical)
              (When  given  together  with  -R.)   For each file,
              either command line operand or  encountered  during
              the  tree walk, that is a symlink, change the group
              ownership of the symlink itself,  rather  than  the
              object  it  points to.  If the system does not sup-
              port a group ownership for symlinks, do nothing for

              a symlink. This is the default.

       -R     Recursively  change the group ownership of directo-
              ries and their contents.

ADDITIONAL GNU DESCRIPTION

       A GNU extension (new in fileutils 4.0) allows one  to  use
       --reference=rfile  as  a group description: the same group
       as that of rfile.

GNU OPTIONS

       -c, --changes
              Verbosely describe the action for each  file  whose
              group actually changes.

       -f, --silent, --quiet
              Do not print error messages about files whose group
              cannot be changed.

       -h, --no-dereference
              Act on symbolic links themselves  instead  of  what
              they point to.  Only available if the lchown system
              call is provided.

       -v, --verbose
              Verbosely describe the action or  non-action  taken
              for every file.

       -R, --recursive
              Recursively  change the group ownership of directo-
              ries and their contents.

GNU STANDARD OPTIONS

       --help Print a usage message on standard output  and  exit
              successfully.

       --version
              Print  version information on standard output, then
              exit successfully.

       --     Terminate option list.

ENVIRONMENT

       The variables LANG, LC_ALL, LC_CTYPE and LC_MESSAGES  have
       the  usual  meaning. For an XSI-conforming system: NLSPATH
       has the usual meaning.

CONFORMING TO

       POSIX 1003.2 only requires the -R  option.  Use  of  other
       options may not be portable.

       This  page  describes  chgrp as found in the fileutils-4.0
       package;  other  versions  may  differ   slightly.    Mail
