Unix and Linux shortcut keys
Shortcuts are designed to help shorten the time required to perform frequently used commands or actions. In the sections below, we have listed keyboard shortcut keys that can be performed by pressing two or more keys at once. We have also listed command line shortcut keys that can be typed at the shell.
Keyboard shortcut keys
Not all of the following shortcut keys are universally compatible with every variant of Unix and Linux. Some of these shortcut keys are designed for use in a terminal environment, while others are for use in a desktop environment.

|Ctrl+B||Moves the cursor backward one character.|
|Ctrl+C||Cancels the currently running command.|
|Ctrl+D||Logs out of the current session.|
|Ctrl+E||Moves the cursor to the end of the line.|

|Ctrl+Q||Turns all output stopped on-screen back on (XON). Also, closes an application window.|
|Ctrl+U||Erases the complete line.|
|Ctrl+W||Deletes the last word typed. For example, if you typed mv file1 file2, this shortcut would delete file2.|

Command line shortcuts
You may find the following command line shortcuts helpful. You may also want to try using the alias command, which allows you to create shortcuts for long or frequently-used commands.
Not all of the following command line shortcuts are universally compatible with every variant of Unix and Linux.
|~||Moves to the user's home directory.|
|!!||Repeats the line last entered at the shell.|
|!$||Repeats the last argument for the command last used. See history command for previous commands.|
