Safe to remove? Hm. Probably no good reason to do so -- just
ln -s /usr/bin/vim /usr/bin/vi
defaults to a symbolic link to /usr/bin/elvis
and you are free to change that as above.
In its original incantation vi
actually is ex
(that would the Unix ex
is just the visual mode of ex
. In your Slackware implementation, ex
is a symbolic link to /usr/bin/vim
(probably don't want to remove it) so, when you type ex
, you're getting vim
in non-visual mode.
If you really want original ex
(so you have original vi
), go to http://heirloom.sourceforge.net/index.html
, download the source and build it (it's actually kind of neat software).
Basically, it ain't broke, don't fix it, eh?
Hope this helps some.
