Re: Line editor without echo...
VIM works perfectly well as a vi variation.
However, a so-called "poweruser" that doesn't check the .rc for local variations of a very customizable editor isn't going to get admin privs on any system that I maintain. Operator error isn't the fault of the program. Or, if you prefer, it's a poor craftsman who blames his tools.
With that said, there's nowt wrong with nvi. Install both. And stevie. And elvis. Etc.
