Well, the commands that I presented (sudo, mount, umount, ps, kill, even lsof) are actually just normal commands that you use to do ordinary things on your system to manage account elevation, mounted disk volumes, processes, and running processes. You need to "memorise" them just as much as you need to memorise their counterparts in a Windows system (Run As/Explorer/Explorer Eject/taskmgr) (...what kind of nerd memorises Ctrl+Alt+Esc anyway?).
...except you don't have lsof, you literally need to install SysInternals Process Explorer.
