Creating a user in Linux is done using terminal commands. You must have root or sudo privileges.

🟢 1️⃣ Create a New User Account

🔹 Command:

sudo useradd username

📌 Example:

sudo useradd student1

👉 This creates the user, but:

• No password is set yet
• Home directory may not be created (depends on system settings)

🟢 2️⃣ Create User with Home Directory

Recommended method:

sudo useradd -m student1

Options:

• -m → Create home directory
• -d → Specify custom home directory
• -s → Specify login shell

Example:

sudo useradd -m -s /bin/bash student1

🟢 3️⃣ Set Password for User

After creating user, set password using:

sudo passwd student1

You will be asked to:

• Enter new password
• Re-enter password

If successful:

passwd: password updated successfully

🟢 4️⃣ Using adduser (Recommended in Ubuntu)

In Ubuntu systems, use:

sudo adduser student2

👉 This command:

• Creates home directory
• Sets password
• Asks for full name and details
• More user-friendly than useradd

🟢 5️⃣ Check User Created

cat /etc/passwd

or

id student1

🟢 6️⃣ Switch to New User

su - student1

or

login student1
