This subchapter looks at w, a UNIX (and Linux) command.
w gives information about current activity on the system, including what each user is doing.
Not to be confused with who, which displays users, but not the processes they are running.
Type w:
$ w
w does not provide information on background processes, which typically account for most of the server usage.
In June 2009, Ken Milberg named this command as one of the Top 50 universal UNIX commands at this web page Top 50 Universal INIX commands. Note that this web page requires agreeing to be spammed before you can read it.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
