  • This is a common use of bind. Hitting any key after will output the key's character sequence. This makes possible using it into a bind command. So pressing ctrl+v and then F2 will output "^[[12~", once binded every time you'll press the function key F2 it will execute your command. Added the \n to make it execute it as well.

What Others Think

bind -x '"\C-l":"ll"' will do the listing without changing anything entered on the current line. Then you can use it in the middle of typing a command.

Stick these keybindings into .inputrc and they'll automatically get sourced. Here's a couple useful snippets from mine: "\e[B": history-search-forward "\e[A": history-search-backward "\el": "ls\n" "\eL": "ls -lh\n" "\ex": "screen -x\n"

The ll assumes that you have an alias such as: alias ll='ls -l' otherwise, you can just do: bind '"\C-l":"ls -l\n"'
