Unix / Linux shortcut keys

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.


Please note that the below shortcut keys and command line shortcuts will not work on all variants of Unix and/or Linux.


KEYBOARD SHORTCUT KEYS


CTRL +B Moves the cursor backward one character.

CTRL +C Cancels the currently running command.

CTRL +D Logs out of the current session.

CTRL +F Moves the cursor forward one character.

CTRL +H Erase one character. Similar to pressing backspace.

CTRL +P Paste previous line and/or lines.

CTRL +S Stops all output on screen (XOFF).

CTRL +Q Turns all output stopped on screen back on (XON).

CTRL +U Erases the complete line.

CTRL +W Deletes the last word typed in. For example,
if you typed 'mv file1 file2' this shortcut would
delete file2.

CTRL +Z Cancels current operation, moves back a directory
and/or takes the current operation and moves it to
the background. See bg command for additional
information about background.


COMMAND LINE SHORTCUTS


~ 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.
