@jedi btw. I just remembered how much PITA it is to memorize commands in any shell. You are staring black screen and googling (with your second computer of course) and people are telling you to read manual. Itīs good advice but to be able to use manual you have to _memorize_ most of the commands and to keep them in your memory you have to use them daily or at least for me this is the case. Add in the mix bad memory and you are in big trouble. One thing that also troubles me is that normally I skip all the option descriptions and search for _examples_ because those are to ones from what I learn immediately. Now I must stop because all the bad memorize start to creep in...
