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".
