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
-f, --silent, --quiet
suppress most error messages
-v, --verbose
output a diagnostic for every file processed
--dereference
affect the referent of each symbolic link (this is the default),
rather than the symbolic link itself
-h, --no-dereference
affect symbolic links instead of any referenced file (useful
only on systems that can change the ownership of a symlink)
--from=CURRENT_OWNER:CURRENT_GROUP
change the ownership of each file only if its current owner
and/or group match those specified here. Either may be omitted,
in which case a match is not required for the omitted attribute
--no-preserve-root
do not treat '/' specially (the default)
--preserve-root
fail to operate recursively on '/'
--reference=RFILE
use RFILE's ownership rather than specifying values RFILE is
always dereferenced if a symbolic link.
-R, --recursive
operate on files and directories recursively
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. '-P' is the default.
-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
--help display this help and exit
--version
output version information and exit
EXAMPLES
chgrp staff /u
Change the group of /u to "staff".
chgrp -hR staff /u
