When I am editing and having a “clumsy fingers” day, I find that I have to reload the file that I am editing from disk repeatedly. I usually just do a quick “:q!” and re-run the vi command that opened the file. But there is a better way!
Use the :edit command:
:edit
Or you can shorten it to
:e
Now if you have typed in the window you are editing and want to reload from disk anyway without saving, remember to add the exclamation point(!) to the command.
:edit!
or
:e!
