who Command who
Print who is logged in
who [file] [am i]
The command who prints the names of the users who are logged in
to the system. For each user, who prints his name, terminal
name, login date, and login time. The form who prints this in-
formation only about yourself.
If file is specified, who uses it instead of /etc/utmp to obtain
information about who is logged in. This is useful, for example,
with the file /usr/adm/wtmp, which contains a continuous record
of logins, logouts and reboots. When file is specified, who dis-
plays logouts; otherwise, they are suppressed.
