NAME

w - Prints a summary of current system activity  

SYNOPSIS

w [-fm] [-h] [-l|-s] [user]

w -u [-m]

The w command prints a summary of the current activity on the system, followed by information about users on the system.
 

DESCRIPTION

The system summary shows the current time, the amount of time since the system was last started, the number of users logged in to the system, and the load averages. The load average numbers give the number of jobs in the run queue for the last 5 seconds, the last 30 seconds, and the last 60 seconds. The Mach factor is a variant of the load average, given for the same intervals; the closer its value to 0 (zero), the higher the load.

The information displayed for each user includes: Who is logged in. What each user is doing. The abbreviated name of the tty or pty each user is on. The location, such as a remote site, from which each user logged in. The time of day each user logged in. The number of minutes since each user last entered data at the keyboard. The name and arguments of the current process. The system unit time used by the current process (PCPU). The system unit time used by all the processes and their children that are associated with the user's tty (JCPU).

If you specify a user, output is restricted to that user.
