The command "add user ${username};" is a shell command that is used to create a new user account on a computer system.

Here's a breakdown of the command:

• "add user": This part of the command instructs the system to add a new user.
• "${username}": This is a placeholder that represents the desired username for the new user account. You would replace "${username}" with the specific username you want to create.
• ";": The semicolon (;) at the end is used to indicate the end of the command.

For example, if you want to create a user with the username "johnsmith", the command would be: "add user johnsmith;". Once executed, the system will create a new user account with the specified username.
