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)
--no-preserve-root: do not treat '/' specially (the default)
--preserve-root: fail to operate recursively on '/'
--reference=,RFILE/: use RFILE's group rather than specifying a GROUP value
-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.

-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".
chgrp -hR staff /u: Change the group of /u and subfiles to "staff".
