Can I rebind EOF in bash/Readline?

Question

I'd like to unbind C-d from sending EOF in bash, and set it to another key. The idea is to keep C-d as EOF in my .bashrc, but to rebind it in my .bash_profile, so that hitting C-d repeatedly with pull me out of any subshells I'm in, but leave me in my login shell.

Is this possible? C-d seems to be bound to delete-char, which it performs if there's text on the current line. It only sends EOF if there's no text on the current line. Rebinding delete-char to, say, C-f applies the delete-char action, but not the EOF sending.

Does Readline offer a way to rebind the EOF command?

Answer 1

The behavior you're talking about is set by stty. Why don't you bind another keystroke to either emit C-d or nothing depending on whether you're in a login shell or a non-login shell and use that?

Answer 2

No, but stty eof will allow you to change the EOF character. And it's a really bad idea to do so.
