Keyboard Shortcuts for Bash ( Command Shell for Ubuntu, Debian, Suse, Redhat, Linux, etc)

The default shell on most Linux operating systems is called Bash. There are a couple of important hotkeys that you should get familiar with if you plan to spend a lot of time at the command line. These shortcuts will save you a ton of time if you learn them. 

 



Ctrl + A Go to the beginning of the line you are currently typing on
Ctrl + E Go to the end of the line you are currently typing on
Ctrl + L               Clears the Screen, similar to the clear command
Ctrl + U Clears the line before the cursor position. If you are at the end of the line, clears the entire line.
Ctrl + H Same as backspace
Ctrl + R Let's you search through previously used commands
Ctrl + C Kill whatever you are running
