If I'm using terminal and typing in a line of text for a command, is there a hotkey or any way to clear/delete that line?
For example, if my current line/command is something really long like:
> git log --graph --all --blah..uh oh i want to cancel and clear this line <cursor is here now>
Is there a hotkey or command to go from the above to:
>
?
Usually I will press the ↓ key, and if my current line is a brand new one on the history, that will clear it. But if I'm going through my command history via the ↑ key and start editing or using those commands, ↓ will only change the prompt to the next newest command in history, so it doesn't work here unless I press ↓ multiple times.
You can use Ctrl+U to clear up to the beginning.
You can use Ctrl+W to delete just a word.
You can also use Ctrl+C to cancel.
If you want to keep the history, you can use Alt+Shift+# to make it a comment.
Bash Emacs Editing Mode Cheat Sheet
Just to summarise all the answers:
Clean up the line: You can use Ctrl+U to clear up to the beginning.
Clean up the line: Ctrl+E Ctrl+U to wipe the current line in the terminal
Clean up the line: Ctrl+A Ctrl+K to wipe the current line in the terminal
Cancel the current command/line: Ctrl+C.
Recall the deleted command: Ctrl+Y (then Alt+Y)
Go to beginning of the line: Ctrl+A
Go to end of the line: Ctrl+E
Remove the forward words for example, if you are middle of the command: Ctrl+K
Remove characters on the left, until the beginning of the word: Ctrl+W
To clear your entire command prompt: Ctrl + L
Toggle between the start of line and current cursor position: Ctrl + XX
Alt + D
Alt + D does not work thats why I have not include it :(
CTRL + L clears the screen but keeps what has been typed in the current command line.
Ctrl + Alt + > moves to the end of the input history which is perfect when you want to cancel searching the history.
I have the complete shortcuts list:
Ctrl+a Move cursor to start of line Ctrl+e Move cursor to end of line Ctrl+b Move back one character Alt+b Move back one word Ctrl+f Move forward one character Alt+f Move forward one word Ctrl+d Delete current character Ctrl+w Cut the last word Ctrl+k Cut everything after the cursor Alt+d Cut word after the cursor Alt+w Cut word before the cursor Ctrl+y Paste the last deleted command Ctrl+_ Undo Ctrl+u Cut everything before the cursor Ctrl+xx Toggle between first and current position Ctrl+l Clear the terminal Ctrl+c Cancel the command Ctrl+r Search command in history - type the search term Ctrl+j End the search at current history entry Ctrl+g Cancel the search and restore original line Ctrl+n Next command from the History Ctrl+p previous command from the History
CTRL + L (16.) preserves the content of the current command line.
Ctrl+h: delete the character before the cursor
Ctrl+A, Ctrl+K to wipe the current line in the terminal. You can then recall it with Ctrl+Y if you need.
Another nice complete list:

to get back what you just erased, Esc and then p :)
echo 'set editing-mode vi' >> ~/.inputrc. Also works in places like python interpreter prompts and some SQL clients
I'm not sure if you love it but I use Ctrl+A (to go beginning the line) and Ctrl+K (to delete the line) I was familiar with these commands from emacs, and figured out them accidently.
An alternative to Ctrl+A, Ctrl+K is Ctrl+E, Ctrl+U.
Ctrl+u: move up to the beginning of your line to a ring buffer
Ctrl+k: move up to the end of your line to a ring buffer
Ctrl+w: move characters and (multiple) words left from your cursor to a ring buffer
Ctrl+y: insert last entry from your ring buffer and then you can use Alt+y to rotate through your ring buffer. Press multiple times to continue to "previous" entry in ring buffer.
CTRL+R and start typing to search for previous commands in history. Will show full lines. CTRL+R again to cycle.
To delete the whole line no matter where the cursor is, you can use the kill-whole-line command, but it is unbound by default. It can be bound to, for example, Ctrl+Alt+K by inserting
"\e\C-k": kill-whole-line
into your Readline init file (conventionally ~/.inputrc).
Various remarks:
To avoid accidentally re-assigning a key sequence that is already in use for something else, you can check all your bindings with bind -P. Check for the suggested binding with bind -P | grep '\\e\\C-k'
The Readline init file name is is taken from the shell variable INPUTRC. If it is unset, the default is ~/.inputrc, or (if that doesn't exist) /etc/inputrc. Notice that if you have ~/.inputrc, /etc/inputrc will be ignored.
To reload your Readline init file, you can use Ctrl+X Ctrl+R.

In order to clean the whole line (2 different ways):
Home , Ctrl+K
End , Ctrl+U
Ctrl+W will clear the word to the left.
Add to the list:
In Emacs mode, hit Esc, followed by R, will delete the whole line.
I don't know why, just happens to find it. Maybe it's not used for delete line but happens to have the same effect. If someone knows, please tell me, thanks :)
Works in Bash, but won't work in Fish.
revert-line readline command: "Undo all changes made to this line". It's bound, by default, to M-r (Meta-R), which can be both Alt-R or Esc R. This means it's not actually deleting the line, only when it was empty to begin with; if you scroll back in your command history and change a command, then issue revert-line, it will change back to the command it was originally and not delete the line.
Alt+# comments out the current line. It will be available in history if needed.
Ctrl+Alt+Backspace for deleting the backward words from the end of the line
Ctrl+Delete for deleting the forward words from the beginning of the line

U/AandYis more like a cut-paste. Try doingCtrl+Ymultiple times.ESCis it's own modifier key in bash. It's used for things like cancelling history navigation (CTRL+r), or swapping the last two words behind the cursor (ESC+t).
