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
-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
