Command-Line Completion
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 then press Tab.
Here are some of the values you can type partially:
Environment variable??”If the text you type begins with a dollar sign ($), the shell
completes the text with an environment variable from the current shell.
Username??”If the text you type begins with a tilde (~), the shell completes the text with
a username.
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.
Hostname??”If the text you type begins with an at (@) sign, the shell completes the text
with a hostname taken from the /etc/hosts file.
To add hostnames from an additional file, you can set the HOSTFILE variable to the
name of that file.
