w


SYNOPSIS
       w [-husfVo] [user]

DESCRIPTION
       w  displays  information  about the users currently on the machine, and
       their processes.  The header shows, in this order,  the  current  time,
       how  long  the  system  has  been running, how many users are currently
       logged on, and the system load averages for the past 1, 5, and 15  min-
       utes.

       The  following entries are displayed for each user: login name, the tty
       name, the remote host, login time, idle time, JCPU, PCPU, and the  com-
       mand line of their current process.

       The  JCPU  time  is the time 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  is  the time used by the current process, named in the
       "what" field.


COMMAND-LINE OPTIONS
       -h   Don't print the header.

       -u   Ignores the username while figuring out the  current  process  and
            cpu  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 time,  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 in which the from field is shown by default.

       -V   Display version information.

       -o   Old style output. Prints blank space for idle times less than  one
            minute.

       user Show information about the specified user only.


ENVIRONMENT
       PROCPS_USERLEN
              Override  the  default width of the username column. Defaults to
              8.

       PROCPS_FROMLEN
              Override the default width of the from column. Defaults to 16.


       The  standard format is DDdays, HH:MMm, MM:SS or SS.CC if the times are
       greater than 2 days, 1hour, or 1 minute respectively.

       For the -o option, the output will be either  DDdays, HH:MM, MM:SSm  or
       blank  if the times are greater than 2 days, 1 hour or 1 minute respec-
       tively.
