Renaming a group in Linux requires superuser (root) privileges since you’ll modify system-level files.

1. Go to the terminal window

Open a terminal window on your Linux system. The terminal application is usually found in t system’s applications menu or by pressing a keyboard shortcut like “Ctrl+Alt+T”.

2. Check the current group name

Before renaming a group, it’s a good practice to verify the current name of the group you want to change. To do this, you’ll use the cat and grep commands.

To check the current group name, use the following command:

cat /etc/group | grep [OLD_GROUPNAME]

here,

• cat: concatenate files and print on the standard output.
• /etc/group: The system file that contains group attributes.
• grep: Searches for patterns in the specified file(s).
• OLD_GROPNAME: Replace this with the current name of the group you want to rename

Rename the Group Using groupmod

To rename a group, you’ll use the groupmod command with the ‘-n’ option to specify the new group name. You’ll also need to provide the old group name, and you’ll typically need superuser privileges.

To rename a group, use the following command:

sudo groupmod -n [NEW_GROUPNAME] [OLD_GROUPNAME]

The sudo command is required because the groupmod command needs root privileges to modify the group database.

here,

• sudo: Allows you to execute a command with superuser privileges.
• groupmod: The command for modifying group definitions on the system.
• -n: This option indicates the new name for the group.
• NEW_GROUPNAME: Replace this with the desired new name for the group.
• OLD_GROUPNAME: Replace this with the current name of the group you want to rename.
