Every time you issue a command in Linux, a new process is launched to run that command. Some of these processes end immediately upon completion of the command. Some may hang around or may spawn additional processes of their own. The command ps -Af will display a listing of all processes running on the same machine as you are. This includes processes being run by lots of other people. Part of the information shown is the name of the command that launched the process. It also will show the login name of the account that launched that process. Try it now and examine its output. What command would you enter to get a count of the number of processes that you personally have running on the machine where you are logged in?
