W(1) Linux User's Manual W(1)
NAME
w - Show who is logged on and what they are doing.
SYNOPSIS
w - [husfV] [user]
DESCRIPTION
w displays information about the users(1,5) currently on the machine, and
their processes. The header shows, in(1,8) this order, the current time(1,2,n),
how long the system has been running, how many users(1,5) are currently
logged on, and the system load(7,n) averages for the past 1, 5, and 15 min-
utes.
The following entries are displayed for each user: login(1,3,5) name, the tty(1,4)
name, the remote host(1,5), login(1,3,5) time(1,2,n), idle time(1,2,n), JCPU, PCPU, and the com-
mand line of their current process.
The JCPU time(1,2,n) is the time(1,2,n) used by all processes attached to the tty.
It does not include past background jobs, but does include currently
running background jobs.
The PCPU time(1,2,n) is the time(1,2,n) used by the current process, named(5,8) in(1,8) the
"what" field.
COMMAND-LINE OPTIONS
-h Don't print the header.
-u Ignores the username while figuring out the current process and
cpu(5,8,8 cpu-ldap) times. To demonstrate this, do a "su" and do a "w" and a "w
-u".
-s Use the short format. Don't print the login(1,3,5) time(1,2,n), JCPU or PCPU
times.
-f Toggle printing the from (remote hostname) field. The default as
released is for the from field to not be printed, although your
system administrator or distribution maintainer may have compiled
a version(1,3,5) in(1,8) which the from field is shown by default.
-V Display version(1,3,5) information.
user Show information about the specified user only.
