who who is on the system [ who-file ] [ ] without an
argument, lists the name, typewriter channel, and login time
for each current UNIX user. Without an argument, examines
the /etc/utmp file to obtain its information. If a file is
given, that file is examined. Typically the given file will
be /usr/adm/wtmp, which contains a record of all the logins
since it was created. Then lists logins, logouts, and
crashes since the creation of the wtmp file. Each login is
listed with user name, typewriter name (with
‘/dev/’ suppressed), and date and time. When an
argument is given, logouts produce a similar line without a
user name. Reboots produce a line with ‘x’ in
the place of the device name, and a fossil time indicative
of when the system went down. With two arguments, behaves as
if it had no arguments except for restricting the printout
to the line for the current typewriter. Thus ‘who am
I’ (and also ‘who are you’) tells you who
you are logged in as. /etc/utmp login (I), init (VIII)
