When logged in to a workstation which retrieves most of its user information from NIS, which command can be used to list ALL the users?

`cat /etc/passwd` will only display users defined in the local password file and will not show users sourced from NIS.

`show users` is not a standard Unix command for listing system users, especially from NIS.

`ypusers list` is not a valid or standard NIS command for listing users; while `ypcat passwd` could list NIS password map entries, `getent passwd` is the more generalized solution.

The `getent passwd` command queries the Name Service Switch (NSS) configuration, which is designed to retrieve user information from all configured sources, including local files (`/etc/passwd`), NIS, or LDAP, thereby providing a complete list of all accessible users.

`cat /var/lib/nis/passwd` would attempt to read raw NIS map files, which are server-side and not directly parsed by clients to list users comprehensively, and this path is not universally standard for client user enumeration.
