w
w
Operating system	Unix and Unix-like
Type	Command

The command w on many Unix-like operating systems provides a quick summary of every user logged into a computer,^[1] what each user is currently doing, and what load all the activity is imposing on the computer itself. The command is a one-command combination of several other Unix programs: who, uptime, and ps -a.

Example

Sample output (which may vary between systems):

$ w
 11:12am up 608 day(s), 19:56,  6 users,  load average: 0.36, 0.36, 0.37
