My editor of choice is
Emacs. However, in a pinch I can
drive vim or
vi just fine1. While I prefer
Emacs, I can’t think of a UNIX-like operating system that ships with
it by default. Most, if not all, do come with something in the
vim/vi family. So, unless I’m going to do some heavy editing on the
server, I usually don’t bother installing Emacs.
Most distros set
vim/vi as the default editor, however I’m seeing
more defaulting to something more “user friendly” like
that, I want set $EDITOR and make sure I get my preferred editor:
What does it do?
type -P prints the full path of the file what Bash
would execute. The
|| works as you would expect, if
a path, execution stops and $EDITOR is set to the value. Otherwise,
the next editor is tried. If nothing is found, then $EDITOR is set to
blank, which will cause the system default to be use.
I started using UNIX in an age when
$EDITOR meant your line editor
that would be used if your terminal didn’t support “advanced”
features, namely full screen cursor control, I still also set:
Even though it’s probably meaningless.
