CHGRP(1)
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 (this is the default), 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 specifying a 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".
- chgrp -hR staff /u
- Change the group of /u and subfiles to "staff".
