Linux Command Library


change group ownership

- Change the owner of a file/folder:
chgrp [group] [path/to/file]

- Recursively change the owner of a folder and its contents:
chgrp -R [group] [path/to/folder]

- Change the owner of a symbolic link:
chgrp -h [user] [path/to/symlink]

- Change the owner of a file/folder to match a reference file:
chgrp --reference=[path/to/reference_file] [path/to/file]

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
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)
do not treat '/' specially (the default)
fail to operate recursively on '/'
use RFILE's group rather than specifying a GROUP value
-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.

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".
