What command must I use in my C or Python program? Thanks for help. L.At the command-line : ps -ef | grep httpd | grep -v grep | wc -l or, better : ps -ef | grep "[h]ttpd" | wc -l (replace by "apache" or "apache2" if needed.) At the program level :find the function that lets you execute a system command and capture it's output, then use the above as command.e.g. in perl you can just do : my $var = `ps -ef | grep "[h]ttpd" | wc -l`;There are a number of more sophisticated alternatives in each programming language, but that's a simple way.

All bets are off if the OP is using Windows. That would require digging into the Windows SDK to enumerate the system task list.
