Created attachment 356490 [details] emerge --info I cannot bind kill-whole-line to ^U. See what happens: j@starfish ~ $ bind -p | grep kill "\C-x\C-?": backward-kill-line "\e\C-h": backward-kill-word "\e\C-?": backward-kill-word # copy-region-as-kill (not bound) "\C-k": kill-line # kill-region (not bound) # kill-whole-line (not bound) "\ed": kill-word # shell-backward-kill-word (not bound) # shell-kill-word (not bound) j@starfish ~ $ bind '"\C-u": kill-whole-line' j@starfish ~ $ asdlkj asd # whole line should be killed^C j@starfish ~ $ bind -p | grep kill "\C-x\C-?": backward-kill-line "\e\C-h": backward-kill-word "\e\C-?": backward-kill-word # copy-region-as-kill (not bound) "\C-k": kill-line # kill-region (not bound) # kill-whole-line (not bound) "\ed": kill-word # shell-backward-kill-word (not bound) # shell-kill-word (not bound) j@starfish ~ $ bind '"\M-u": kill-whole-line' j@starfish ~ $ bind -p | grep -- -u "\e~": complete-username "\C-x~": possible-username-completions "\C-x\C-u": undo "\C-u": unix-line-discard j@starfish ~ $ bind '"\C-]": kill-whole-line' j@starfish ~ $ <====================== Whole line killed with ^]. OK j@starfish ~ $ bind -r '"C-u"' <===== Removing ^U binding j@starfish ~ $ bind -p | grep C-u "\C-x\C-u": undo "\C-u": unix-line-discard <===== ^U binding still here Conclusion: ----------- - Unbinding does not work - Binding a key that already exists cannot be reassigned
i'm almost certain this is due to your tty settings and not bash/readline $ man stty kill CHAR CHAR will erase the current line $ stty -a | grep -o 'kill[^;]*' kill = ^U so you first need to change your tty settings with `stty`, and then use bash's `bind` to set it to something else
