Random Tricks

  • Read the output of a bash command
    :read !bashcommand <CR>

  • Copy/paste from one session to another

In source file (start in normal mode):

  1. Use ma to mark first line
  2. Use mb to mark last line
  3. Use :'a,'b w! xfer to write out range to a scratch file

In destination file:

  1. Move cursor to desired paste location
  2. Ensure you're in normal mode
  3. Use :r xfer to read in text
  • Search and Replace Tricks
  1. Capture Groups: enclose portion between \( and \), refer to it with \1, \2, etc. sequential.
  2. Visual Mode: v, select desired text, :s (will create a command that looks like '<,'>s/find/replace with/flags)
  3. Scope: :s refers to current line, :5,9s refers to lines 5-9 inclusive, :%s refers to entire file.
    Examples:
    '<,'>s/,\(\d\),/, \1,/g looks for a comma followed by a single digit followed by another comma and inserts a space between the first comma and the digit. Command will apply to a visual selection.
  • Put Vim in the background and execute some terminal commands <Ctrl-z> Run terminal commands $ fg to go back to Vim.
