Linux – Add, Delete and Modify Users (adduser, deluser, passwd, chfn)

Managing Users on Linux systems is very easy.

Add Users

• sudo adduser username – adds users
• Additional profile information is not required, but a comment is a good idea.

Delete Users

• sudo deluser username – deletes the user, but not the profile folder
• sudo rm -rf /home/username – deletes profile folder

User Account File

• vim /etc/passwd – allows you to view the user account file

Changing Passwords

• passwd – changes your pasword
• sudo passwd username – changes password for another account

Change User Profiles

• sudo chfn username – changes profile information for user accounts.

Locking Accounts and Other Tasks

• sudo usermod -option username – allows you make some additional changes to user account abilities such as locking and unlocking accounts.
