You are most welcome. Probably hundreds but I don't know what you don't know. It's worth learning some old-school command-line history fu as well because that is often useful. I've written up some things I have found helpful here[1]
One thing which is not in the writeup but should be (and I mention it in a sibling thread) is "rlwrap" which is a readline wrapper which imbues whatever program with readline editing and history niceness.
So say you have to use some crufty cli like a sql cli or something that doesn't have commandline editing or history. You run "rlwrap horrible_sql_cli" aaand now it does. Really helpful.
