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

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

       w - [husfiV] [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 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.

       -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.

       -i   Display IP address instead of hostname (if possible)

       -V   Display version information.

       user Show information about the specified user only.

              information about who is currently logged on

       /proc  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  by  Larry  Greenfield  <green-> and Michael K. Johnson <>.
