No, I'm working with some serious ignorance here. So the smallest thing is profound enlightenment. For example, it is well known that "background processes" can't use the terminal interface. But try start several xterm& (background xterms) and you will still get several fully functional xterm windows. I knew the window manager can all start from a single xterm and "spawn" an eyefull. Try this a couple of times from a single terminal and consider all the inherited environment and file descriptors -->> > xterm&; xterm&; xterm&; And all the command line arguments certainly provide different functionality to the hidden protected command object. When a half baked programmer like me can't figure out what he programs, how can the user?? At least I can keep it small and simple.
