You need to use the ps command. ps will give you, by default,
only the list of programs running under your account ... and you
probably want to know ALL programs running. ps comes to the
rescue, though: I frequenly use -ef to show all fields and for all
users. If you're looking for all programs of a particular name,
filter through ps's output by piping it to grep. If you want to count
the number of programs that match a particular grep filter, pipe
grep's output to wc -l. Here are some examples:
The | is just a Shift+\.Code:ps // show all programs running under your login
ps -ef // show all programs running on the system
ps -ef | grep apache // show all programs running that have the
// phrase 'apache'
ps -ef | grep apache | wc -l // show the count of above
