Get current swap usage for all running processes Based on a bash scr ipt by Erik Ljungstrom 27/05/2011 Author = Christopher Ranschaert - 07/07/2012 Parses pids in /proc, collects the name from /proc/$pid/comm and calculates the swapsize from /proc/$pid/smaps Warning: Needs root permissions to read swap values, will otherwise return 0. If you don't trust this, learn some Perl and check the code :-)
