    Well, today I learned that set -o vi is going into all my .bashrc’s from now on.

      One thing I’ve found useful is ctrl+x ctrl+e to edit the current command in $EDITOR. That way I can leave the emacs-style keybindings at the shell, as you’ll find that everywhere, but you can still edit unwieldy commands in real vim.

      Best part: Bash has it by default.

      1. 1

        Or, in your /etc/inputrc or ~/.inputrc:

        set editing-mode vi
        set keymap vi-command

        In some situations (such as the set operations or uniqueness operations below) you can safely ignore slow i18n routines entirely and use traditional byte-based sort order, using export LC_ALL=C.

        Be very careful if you do this. I highly recommend you don’t export it and instead use it as the environment for a single command.

        LC_ALL=C sort blah
        

        If you export it, you’ll likely to forget that you did and you’ll run into all kinds of trouble.
