chgrp Command: Tutorial & Examples

Change the group ownership of a file or directory

The chgrp command is a Linux command that allows you to change the group ownership of a file or directory. It stands for "change group."

To use the chgrp command, you need to specify the name of the group that you want to assign to the file or directory, and then the name of the file or directory that you want to change. For example:

chgrp groupname /path/to/file

This command will change the group ownership of the file /path/to/file to groupname.

You can also use the -R option to recursively change the group ownership of all files and directories within a directory. For example:

chgrp -R groupname /path/to/directory

This command will change the group ownership of the directory /path/to/directory and all of its contents (including subdirectories and files) to groupname.

Note that you must be the owner of the file or directory, or have superuser privileges (using the sudo command), to use the chgrp command.
