chgrp - change group ownership
chgrp [OPTION]... GROUP FILE...
chgrp [OPTION]... --reference=RFILE FILE...
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
