You can remove a Linux user using the userdel command. The userdel delete/remove a user account and related files from the Linux server. Use this command to modify the system account files. It delete all entries that refer to the given user name. Usually, user info removed from the /etc/passwd, [/etc/shadow[/file], and /etc/group files.

  1. Open the Terminal app. Log in to your server using ssh command:
    ssh user@server-name-here
  2. Run the userdel command to remove the old user named tom:

How to remove a Linux user

The syntax is as follows to remove a user account and related files:
userdel userNameHere
userdel -f userNameHere
userdel -r userNameHere
userdel -Z user-name-here

Where options are as follows for the command:

  • -f – This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user’s home directory and mail spool, even if another user uses the same home directory or if the specified user does not own the mail spool.
  • -r – Files in the user’s home directory removed along with the home directory itself and the user’s mail spool. Files located in other file systems will have to be searched for and deleted manually.
  • -Z – Remove any SELinux user mapping for the user’s login. Useful on Fedora, RHEL, CentOS and other distro where SELinux used.

Warning: Be careful with the userdel command. It delete a user’s home directory/files. Always keep backups.

# grep ^Jerry /etc/passwd

You have to delete home directory and other files manually using rm command:

# rm -rf /home/Jerry
