To save you a few keystrokes, the bash shell offers several different ways of completing partially typed values. To attempt to complete a value, type the first few characters and press Tab. Here are some of the values you can type partially from a bash shell:

 Command, alias, or function If the text you type begins with regular characters, the shell tries to complete the text with a command, alias, or function name.

 Variable If the text you type begins with a dollar sign ($), the shell completes the text with a variable from the current shell.

 Username If the text you type begins with a tilde (~), the shell completes the text with a username. As a result, ~username indicates the home directory of the named user.

 Hostname If the text you type begins with the at symbol (@), the shell completes the text with a hostname taken from the /etc/hosts file.
