Unix tricks

Bash

  • ctrl-r searches your command history as you type
  • Add set -o vi in your ~/.bashrc to make use the vi keybindings instead of the Emacs ones. Takes some time to get used to, but it's fantastic!
  • Input from the commandline as if it were a file by replacing command < file.in with command <<< "some input text"
  • '^' is a sed-like operator to replace chars from last command ls docs; ^docs^web^ is equal to ls web The second argument can be empty.
