about local and remote system users. By default, the following information
is displayed about each user currently logged-in to the local host:
Idle time is in minutes if it is a single integer, hours and
minutes if a ‘
:’ is present, or days
if a ‘d’ is present. Login time is displayed as the day name
if less than six days, else month, day, hours and minutes, unless more than
six months ago, in which case the year is displayed rather than the hours
The names of terminals for which write permission is denied (see mesg(1)) are prepended with an asterisk (‘*’). Unknown devices as well as nonexistent idle and login times are displayed as single asterisks.
The options are as follows:
-soption is also specified, the name of the remote host is displayed instead of the office location and office phone.
-soption as well as the user's home directory, home phone number, login shell, mail status, and the contents of the “.plan” and “.project” files from the user's home directory.
If idle time is at least a minute and less than a day, it is presented in the form “hh:mm”. Idle times greater than a day are presented as “d day[s]hh:mm”.
Phone numbers specified as eleven digits are printed as “+N-NNN-NNN-NNNN”. Numbers specified as ten or seven digits are printed as the appropriate subset of that string. Numbers specified as five digits are printed as “xN-NNNN”. Numbers specified as four digits are printed as “xNNNN”.

“(messages off)” is appended to the line containing the
device name. One entry per user is displayed with the
-l option; if a user is logged on multiple
times, terminal information is repeated once per login.
Mail status is shown as “No Mail.” if there is no mail at all, “Mail last read DDD MMM ## HH:MM YYYY (TZ)” if the person has looked at their mailbox since new mail arriving, or “New mail received ...”, “Unread since ...” if they have new mail.
