useradd Command

The useradd command in Linux is used to create a new user account. The command is typically used by system administrators to add new users to a Linux system.

Here are some examples of how to use the useradd command:

To add a new user account called “john” with a default home directory, you can use the command useradd john
To specify a custom home directory for the new user, you can use the -d option, like this: useradd -d /home/john john
To specify a specific user group for the new user, you can use the -g option, like this: useradd -g users john
To specify a specific UID for the new user, you can use the -u option, like this: useradd -u 500 john
To add a new user with a specific shell, you can use the -s option, like this: useradd -s /bin/bash john

Once a user is added, the default password for the user is locked, and you can set new password using passwd command.

Example :

$ useradd -m -s /bin/bash -g users -u 500 john

This command creates a new user account called “john” with a home directory, a default shell of /bin/bash, a primary group of “users”, and a UID of 500. Additionally, the option -m creates the home directory for the user.
