W(1)                          Linux User's Manual                         W(1)

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

       w - [husfV] [user]

       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-

       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.

       -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

       -s   Use the short format.  Don't print the login(1,3,5) time(1,2,n),  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(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.

              information about who is currently logged on

       /proc(5,n)  process information

       free(1), ps(1), top(1), uptime(1), utmp(5), who(1)

       w was re-written almost entirely by Charles Blake, based on the version(1,3,5)
       by Larry Greenfield <> and Michael K. Johnson
