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
