ps aux I can get list running processes with command associated with them, e.g.
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND _windowserver 142 2.0 1.3 4559968 224672 ?? Ss 7:11AM 33:21.95 /System/Library/PrivateFrameworks/SkyLight.framework/Resources/WindowServer -daemon lrogalsk 6419 1.9 0.5 2703580 77588 ?? S 2:15PM 0:40.88 /Applications/Utilities/Terminal.app/Contents/MacOS/Terminal ...
COMMAND includes command line arguments and absolute path of file, both of which may contain spaces. How can I get process name in deterministic manner?
