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 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 minutes.

       The  following  entries are displayed for each user: login
       name, the tty name, the  remote  host,  login  time,  idle
       time,  JCPU,  PCPU,  and the command 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.

       user Show information about the specified user only.
