4.7. Typing Shortcuts

If you've been following along with this tutorial at your terminal, you may be tired of typing the same things over and over again. It can be particularly annoying when you make a mistake and have to start over again. Here is where the shell really makes life easier. It doesn't make Unix as simple as a point-and-click interface, but it can help you work really fast in a command environment.

This section discusses command-line editing. The tips here work if your shell is bash, ksh, tcsh, or zsh. Command-line editing treats the last 50 or so lines you typed as a buffer in an editor. You can move around within these lines and change them the way you'd edit a document. Every time you press the Return key, the shell executes the current line.
