This question gets to the root of how you want to work - so there's some "preference" that may be in play. If you come from the school of
vi you might prefer a command as opposed to the emacs key bindings.
I prefer using
fc since my big chunk of time post-emacs was spent in Korn shell (ksh) and I used
fc built in to summon the editor. On all macOS systems, by default
vim is chosen over the
For changing the editor, I usually set FCEDIT so that it catches both the bash / emacs invocation for the
fc built in commands. I rarely change things, though since it's nice to know I can get directly to emacs when needed (on occasion it's better for me) and let
fc do the heavy lifting for me. So if I were to head back to “emacs land”,
fc is how I'd get there initially.
