I just recently discovered that bash has keyboard shortcuts to help you move around and edit things faster. Here’s the list of some of my favorites.
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 + F: Forward one character.
Ctrl + B: Backward one character.
Meta + F: Move cursor forward one word on the current line
Meta + B: Move cursor backward one word on the current line
Ctrl + P: Previous command entered in history
Ctrl + N: Next command entered in history
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: Lets you search through previously used commands
Ctrl + C: Kill whatever you are running
Ctrl + D: Exit the current shell
Ctrl + Z: Puts whatever you are running into a suspended background process. fg restores it.
Ctrl + W: Delete the word before the cursor
Ctrl + K: Kill the line after the cursor
Ctrl + Y: Yank from the kill ring
Ctrl + _: Undo the last bash action (e.g. a yank or kill)
Ctrl + T: Swap the last two characters before the cursor
Meta + T: Swap the last two words before the cursor
The list goes on and if you want to know more take a look at bash reference
To be able to search through bash command history using up and down arrows add following script to your
"\e[A": history-search-backward "\e[B": history-search-forward set show-all-if-ambiguous on set completion-ignore-case on
Like the single most useful thing in bash explains:
type “cd /“ and press the up arrow and you’ll search through everything in your history that starts with “cd /“.
