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.
