UNIX/LINUX Command – w

Last updated Apr 27, 2021


w—Present who users are and what they are doing


w [-hin] [-user]


The w utility prints a summary of the current activity on the system, including what each user is doing. The first line displays the current time of day, how long the system has been running, the number of users logged into the system, and the load averages. The load average numbers give the number of jobs in the run queue averaged over 1, 5, and 15 minutes.

The fields output are the user’s login name, the name of the terminal the user is on, the host from which the user is logged in, the time the user logged on, the time since the user last typed anything, and the name and arguments of the current process.

The options are as follows:
-h              Suppress the heading
-i               Output is sorted by idle time
-n              Show network addresses as numbers
-w              Interpret addresses and attempt to display them symbolically

If a username is specified, the output is restricted to that user.
