.SH DESCRIPTION
|
|
.PP
|
|
\fIWho\fR prints a list of currently logged in users. For each one,
|
|
the user name, terminal, and login time is printed.
|
|
This program gets its information from the file \fI/etc/utmp\fR, which
|
|
is updated by init and login.
|
|
If the file does not exist, neither of these will create it, and
|
|
\fIwho\fR will not work. Note that if you decide to create an empty
|
|
\fI/usr/adm/wtmp\fR to enable the login accounting, it will grow forever and
|
|
eventually fill up your disk unless you manually truncate it from time to time.
|
|
If an optional file name is provided, the logins in that file will be printed.
