Find the group name of the folder in UNIX / Linux

You can find the group name of a folder in Unix or Linux using the ls command with the -l option. The -l option displays the details of a file or folder, including its permissions, owner, group, size, and modification time.

Here's an example:

ls -l folder_name

Output:

drwxr-xr-x 2 user group 4096 Jan 1 12:34 folder_name

In this example, the group name is group.

You can also use the stat command to display detailed information about a file or folder, including its group name:

stat folder_name | grep Group

Output:

 Group: group (100)

In this example, the group name is group.
