$ users

$ users [/var/log/wtmp]

users [file]

users prints a compact, space-separated list of usernames currently logged into the system. If a user has multiple login sessions, their name appears once for each session.
The command reads from /var/run/utmp by default to determine who is logged in. An alternate utmp-format file can be specified as an argument, such as /var/log/wtmp to see historical logins.
Unlike who and w, which provide detailed information about each session, users produces minimal output suitable for quick checks or scripting where only the list of logged-in usernames is needed.

file

Alternate utmp file.
