NAME
chgrp - change group ownership
SYNOPSIS
chgrp
[OPTION]... GROUP FILE...
chgrp
[OPTION]... --reference=RFILE FILE...
DESCRIPTION
Change the group of each FILE to GROUP.
With --reference, change the group of each FILE to that of RFILE.
-c, --changes
like verbose but report only when a change is made
--dereference
affect the referent of each symbolic link, rather
than the symbolic link itself (this is the default)
-h, --no-dereference
affect each symbolic link instead of any referenced
file (useful only on systems that can change the
ownership of a symlink)
--no-preserve-root
do not treat `/' specially (the default)
--preserve-root
fail to operate recursively on `/'
-f, --silent, --quiet
suppress most error messages
--reference=RFILE
use RFILE's group rather than the specifying
GROUP value
-R, --recursive
operate on files and directories recursively
-v, --verbose
output a diagnostic for every file processed
The following options modify how a hierarchy is traversed when the -R
option is also specified. If more than one is specified, only the final
one takes effect.
-H
if a command line argument is a symbolic link
to a directory, traverse it
-L
traverse every symbolic link to a directory
encountered
-P
do not traverse any symbolic links (default)
--help
display this help and exit
--version
output version information and exit
EXAMPLES
chgrp staff /u
Change the group of /u to "staff".
