W(C) XENIX System V W(C)
Name
w - Displays information about who is on the system and what
they are doing.
Syntax
w [-hlqtw] [-n namelist] [-s swapdev] [-c corefile] [-u
utmpfile] [users...]
Description
w prints a summary of the current activity on the system,
including what each user is doing. The heading line shows
the current time of day, how long the system has been up,
the number of users logged onto the system, and load
averages. Load averages are the number of processes in the
run queue averaged over 1, 5, and 15 minutes.
The options are:
-h Don't print the heading or title lines.
-l Long format (default): For each user, w outputs the
user's login name, the terminal or pseudo terminal the
user is currently using, when the user logged onto the
system, the number of minutes the user has been idle
(how much time has expired since the user last typed
anything), the CPU time used by all processes and their
children attached to the terminal, the CPU time used by
the currently active process, and the name and
arguments of the currently active process.
-q
Quick format: For each user, w outputs the user's login
name, the terminal or pseudo terminal the user is currently
using, the number of minutes the user has been idle, and the
name of the currently active process.
-t
Only the heading line is output (equivalent to uptime(C)).
-w
Both the heading line and the summary of users is output.
-nnamelist
The argument is taken as the name of an alternate namelist
( /xenix is the default).
-sswapdev
Uses the file swapdev in place of /dev/swap. This is useful
when examining a corefile.
-ccorefile
Uses the file corefile in place of /dev/kmem.

W(C) XENIX System V W(C)-uutmpfile
The file utmpfile is used instead of /etc/utmp as a record
of who is currently logged in.
If any users are given, the user summary is restricted to
reporting on those users.
Files
/xenix
/etc/utmp
/dev/kmem
/dev/swap

Notes
The ``currently active process'' is only an approximation
and is not always correct. Pipelines can produce strange
results, as can some background processes. If w is
completely unable to guess at the currently active process,
it prints ``-.''
