Bind to execute command with last argument of previous command

Question

I want to create a bind that executes g++ !$ in the same way that the shell would interpret it if I just typed it.

I tried:

• bind '"\ee": "g++ !$"', but it doesn't execute command (just "pastes" it)
• bind -x '"\ee": "g++ !$"', but it doesn't interpret the !$ part correctly

Any way to overcome it without using some custom shell scripts?

Answer 1

bind '"\ee": "g++ !$"' does exactly what you wrote, which is to insert g++ !$ on the command line. If you want the command to be executed, you need to press Enter.

bind '"\ee": "g++ !$\r"'
