Unix and Linux shortcut keys

Introduction

Shortcuts are designed to help shorten the time required to perform frequently used commands or actions. In the below sections we have listed keyboard shortcut keys that can be performed by pressing two or more keys at once. In addition to keyboard shortcut keys, we have also listed command line shortcut keys that can be typed in at the shell.
Tip: Not all of the below shortcut keys and command line shortcuts will not work on all variants of Unix and Linux.

Keyboard shortcut keys

CTRL+BMoves the cursor backward one character.
CTRL+CCancels the currently running command.
CTRL+DLogs out of the current session.
CTRL+FMoves the cursor forward one character.
CTRL+HErase one character. Similar to pressing backspace.
CTRL+PPaste previous line(s).
CTRL+SStops all output on screen (XOFF).
CTRL+QTurns all output stopped on screen back on (XON).
CTRL+UErases the complete line.
CTRL+WDeletes the last word typed in. For example, if you typed 'mv file1 file2' this shortcut would delete file2.
CTRL+ZCancels current operation, moves back a directory or takes the current operation and moves it to the background. See bg command for additional information about background.

Command line shortcuts

In addition to the below command line shortcuts, it is also helpful to use the alias command that allows you to specify a keyword for frequently used commands or mistakes.
 ~Moves to the user's home directory.
!!Repeats the line last entered at the shell. See history command for previous commands.
!$Repeats the last argument for the command last used. See history command for previous commands.
resetResets the terminal if terminal screen is not displaying correctly.
shutdown -h nowRemotely or locally shuts the system down.
