Hotkeys in Bash helps you use Bash more efficiency. Most of them have slower analogs. But some of them help you easier do common things.
Ctrl + a
– Return to the start of the command you’re typing
Ctrl + e
– Go to the end of the command you’re typing
Ctrl + u
– Cut everything before the cursor to a special clipboard
Ctrl + k
– Cut everything after the cursor to a special clipboard
Ctrl + y
– Paste from the special clipboard that Ctrl + u and Ctrl + k save their data to
Ctrl + t
– Swap the two characters before the cursor (you can actually use this to transport a character from the left to the right, try it!)
Ctrl + w
– Delete the word / argument left of the cursor
Ctrl + h
– Delete the one symbol left of the cursor
Ctrl + l
– Clear the screen
Now you are more efficient in Bash than you were before.
