If you type something wrong on a command line, the bash shell ensures that you don't have to delete the entire line and start over. Likewise, you can recall a previous command line and change the elements to make a new command.

By default, the bash shell uses command-line editing that is based on the emacs text editor. (Type man emacs to read about it, if you care to do so.) If you are familiar with emacs, you probably already know most of the keystrokes described here.
