What is usermod?
- One of the many Linux commands available to system administrators for managing users is the usermod command.
- It is used to change the username, password, location of the user's home directory, default shell, and other details of an existing user account.
- In Linux, the usermod command, also known as modify user, is used to update a user's properties via the command line.
- We use the Usermod command to modify a user's properties after they have been created, such as their password or login directory.
- Usermod and useradd are different in that the latter is used to alter existing users while the former is used to add new users.
- While useradd has the ability to set a Linux user's preferences, it only does so for newly created users.
- For more information on the useradd command, see our Linux Users and Groups page.
