Some VIM tricks

Apply some vim commands on a file without entering vim

E.g. given 1st line "what to edit" and 2nd line "what vim commands to execute"

  • -E Ex mode: vim will treat STDIN as if it's just list of commands
  • here ^E means key press, so here 2 strategies to deal with it
    • replace ^E with new_line + ":norm "
    • replace ^E with hex code of ESC which is \x1b
