       w - Show who is logged on and what they are doing.

       w - [husfV] [user]

       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-

       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.

       -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

       -s   Use the short format.  Don't print the login time, JCPU  or  PCPU

       -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.
