Check if the user has been successfully created in Linux.

To check if a user has been successfully created on a Linux system, you can use one of the following commands:

1. The command “cat /etc/passwd” will display all users on the system. If you find the user you created in the list, then the user has been successfully created.
2. id username: Replace username with the username of the user you have created. If this command returns the user’s UID and the group ID they belong to, it means the user has been successfully created.
3. Replace “username” with the username of the user you have created. If the command returns the user’s information, it means the user has been successfully created.

These commands will display the basic information of the user, such as username, UID, GID, shell, etc. If the user appears and the information is correct, it means the user has been successfully created.
