Oh! Editor wars! Not been in one of these for a while ;^)<br>
<br>
I use vi and emacs, depending upon what I'm doing. If I'm doing some code hacking, then emacs is my editor of choice, especially under X. Best syntax highlighting of any other editor, IMHO.<br>
<br>
If I'm doing a quick hack of, for eg, a system text file, then vi is brought into play. Quick to load, and quick to use once you get to know it. I think it's also got a better search and replace than any other editor. (Come on, how can you beat ':1,$ s/string_to_find/string_to_replace_with/g'? ;^)<br>
<br>
Of course, they both have a bit of learning curve, and you get out what you put in.<br>
<br>
BTW, ex is a line based editor that vi sits on top of. Whenever you enter a ':' command in vi, you are actually entering an ex command.<br>
<br>
HTH.
