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
- 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)
- do not treat ‘/’specially (the default)
- fail to operate recursively on ‘/’
- -f, –silent, –quiet
- suppress most error messages
- 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 thefinal one takes effect.
- if a command line argument is a symbolic link to a directory, traverse it
- traverse every symbolic link to a directory encountered
- do not traverse any symbolic links (default)
- display this help and exit
- output version information and exit
- chgrp staff /u
- Change the group of /u to “staff”.
- chgrp -hR staff /u
- Change the group of /u and subfiles to “staff”.
