W(1)                                                User Commands                                                W(1)



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

SYNOPSIS
       w [options] 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, --no-header
              Don't print the header.

       -u, --no-current
              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, --short
              Use the short format.  Don't print the login time, JCPU or PCPU times.

       -f, --from
              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.

       --help Display help text and exit.

       -i, --ip-addr
              Display IP address instead of hostname for from field.

       -V, --version
              Display version information.

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

       user   Show information about the specified user only.
