useradd
The "useradd" command line tool is used in Unix-like operating systems to create a new user account. It is commonly used by system administrators to add new users to the system. By using the "useradd" command followed by the username, the tool creates a new entry in the system's user database. Additionally, the command creates a home directory for the user and assigns the default user group to them. The user's login name, user ID, and group ID can be specified as optional parameters during the creation process. The tool also provides various options to customize account settings such as password expiry, shell access, and user groups. Overall, the "useradd" command line tool simplifies the process of creating new user accounts on Unix-like systems.
