Bash does not recognize Control-R

[Greg Reagle]

One of the most useful features of Bash, for me, is
reverse-search-history which is bound to Control-R aka ctrl-r aka
"\C-r". This does not work for me in Minix. I am using QEMU on Linux.
Bash seems to completely ignore Control-R. Control-S works fine in
Bash. In Nano, Control-R works fine.

I bound reverse-search-history to Meta-R by putting this in my
~/.inputrc "Meta-r: reverse-search-history" and it works fine as Alt-R.
So I can use reverse-search-history, but why doesn't it work on the
key that my brain is already programmed to use?

By the way, I am running bash after logging in with the default shell,
in case that is relevant.

Thank you.

Does it work if you bind "manually" (in ~/.inputrc) like in
ctrl-r: reverse-search-history

If it does, I would say this is a problem with the way bash is packaged.

No. I don't think the problem is with the binding. It's just that bash
doesn't seem to see ctrl-r. For instance typing ctrl-q (quote the
following character) followed by ctrl-r does nothing.

Thanks for the suggestion, I hadn't tried it before you suggested it.

Make sure another application isn't sucking up your ctrl-R shortcut.
