How to Create a User Group in Linux
How to Create a User Group in Linux
Hey there! 👋 Welcome back to ProgramGuru.org. In this Linux tutorial, we're going to learn how to create a user group. This is an essential part of managing permissions and organizing users on any Linux system. Don’t worry if you’re new—I'll guide you step by step.
🚀 What is a User Group?
In Linux, a group is a collection of users. Groups help system administrators manage permissions efficiently. For example, instead of setting permissions for each user, you can assign permissions to a group and add users to that group.
🛠️ Step 1: Open the Terminal
Let’s begin by opening your terminal. You can do this with:
Ctrl + Alt + T
🔹 Step 2: Check Existing Groups (Optional)
If you want to see the current groups on your system:
cut -d: -f1 /etc/group
root
daemon
bin
sys
...
✅ Step 3: Create a New Group
We’ll use the groupadd
command to create a new group. For example, to create a group named devteam
:
sudo groupadd devteam
You’ll be prompted for your password if you’re not the root user.
🔍 Step 4: Verify the Group Was Created
Let’s check if the group was successfully created:
getent group devteam
devteam:x:1002:
This means the group exists and currently has no users.
👤 Step 5: Add a User to the Group
To add an existing user (like john
) to the new group:
sudo usermod -aG devteam john
The -aG
flag appends the user to the group without removing them from others.
🔁 Step 6: Apply Group Changes
To make group changes take effect, either log the user out and back in, or use:
newgrp devteam
📋 Step 7: Confirm User's Groups
You can confirm the user's group membership with:
groups john
john : john devteam
🎉 That’s It!
You’ve successfully created a new user group and added a user to it. Group management is key to secure and scalable Linux system administration.
