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.
-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.
environment

Override the default width of the username column. Defaults to 8.
