- Change the owner group of a file/directory:
chgrp group path/to/file_or_directory
- Recursively change the owner group of a directory and its contents:
chgrp -R group path/to/directory
- Change the owner group of a symbolic link:
chgrp -h group path/to/symlink
- Change the owner group of a file/directory to match a reference file:
chgrp --reference=path/to/reference_file path/to/file_or_directory
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".
