I used to have a co-worker who was really good at UNIX.
He showed me how to use Vi key bindings to edit my shell commands.
He placed the command in a file that ran every time I logged in.
Since then, I've moved to a different project.
Unfortunately I don't remember how to set this up.
Is there anyone here who knows how to use Vi key bindings to edit commands in the terminal?
How can I make that setting permanent?
