chgrp(1)


chgrp -- change the group ownership of a file

Synopsis

chgrp [-R] [-h] group file ...

Description

chgrp changes the group ID of the files given as arguments to group. The group may be either a decimal group ID or a group name found in the group ID file, /etc/group.

You must be the owner of the file, or have appropriate privilege to use this command.

The operating system has a configuration option (_POSIX_CHOWN_RESTRICTED), to restrict ownership changes. When this option is in effect, the owner of the file may change the group of the file only to a group to which the owner belongs. Only a privileged user can arbitrarily change owner IDs whether this option is in effect or not.

chgrp has two options:


-R
Recursive. chgrp descends through the directory, and any subdirectories, setting the specified group ID as it proceeds. When symbolic links are encountered, they are traversed.

-h
If the file is a symbolic link, change the group of the symbolic link. Without this option, the group of the file referenced by the symbolic link is changed.

The LC_CTYPE environment variable determines the codesets used in the arguments (see LANG on environ(5)).

Files


/etc/group

/usr/lib/locale/locale/LC_MESSAGES/uxcore.abi
language-specific message file (see LANG on environ(5)).
