Which command can you use to list all user accounts in Linux?

The command to list all user accounts in Linux is cat /etc/passwd. This is correct because the /etc/passwd file contains essential information about the user accounts on a Linux system, including usernames, user IDs, and other details. By using the cat command, you can display the contents of this file directly in the terminal, allowing you to see all available user accounts. This file is fundamental in Linux systems for user management, and it is where user account information is stored.

The other options do not represent valid commands in Linux for listing user accounts. "list users," "show accounts," and "get user list" are not recognized commands in the Linux command line interface. Instead, they may sound like commands one might expect in a different system or application, but they do not exist in standard Linux usage. Therefore, the only accurate and functional choice for this task is cat /etc/passwd.
