Sounds easy theoretically but this stuff almost never seems to work for me. I get some error or the other when trying these commands and all.
I did not try any of these though. I was just speaking from my past experiences. And anyway, I just won't deal with text based commands. Why should I! It is a matter of preference. I bought a high-end expensive machine for myself in the twenty-first century not to type (or copy-paste) text commands on a bland screen. That is thoroughly unacceptable.
Of course, some people prefer it so I guess it is useful stuff for them. I'm not saying anything against it, but it is definitely not for me. If some tip involves clicking here and there and getting things done, I'm all for it. But tell me to type an alphabet into a scary looking screen and I'm out of it.
