In bash the Ctrl+r command is very useful, I type Ctrl+r whatever and it searchs my history for commands containing the word whatever. But if I type whatever and realize that I would like search that word and hit Ctrl+r nothing happens.

Is there a way hitting a key and having it behaving as if I had typed Ctrl+r whatever instead of whatever Ctrl+r?

I have the following in my .inputrc:

"\C-p": history-search-backward

but this only works if the beginning of the line is the same.

You can search bash's history using what you have already typed easily.

Suppose you have just typed curl -I http://superuser.com and you forgot to type Ctrl+r first:

$ curl -I http://superuser.com

If you want to do an i-search on your history, go to the beginning of line first (Ctrl+a), enter i-search (Ctrl+r) and type Ctrl+y. This should search using the contents of the whole text you already typed:

(reverse-i-search)`curl -I http://superuser.com': curl -I http://superuser.com/faq

Alternatively, you can use Ctrl+w instead of Ctrl+y to search using just the first word of the text you just typed:

(reverse-i-search)`curl': curl -I http://superuser.com/faq

Binding it all to a single key

If you want to do all this in one keystroke, you can bind a single key to a keyboard macro. If you want to use, say, F12 run:

$ bind '"\e[24~":"\C-a\C-r\C-y"'

That will last for the session.

Making it permanent

Just define the macro in your ~/.inputrc:


Note that here we omit the single quotes.

    I am not sure if it is a problem with my configuration, but after I type c-r typing c-y does not paste anything there. If I type c-y by itself just pastes the text, so I cannot combine the two commands...

  • Do you go to beginning of line first? (C-a)

    You are right, I wasn't going to beginning of line. Now I have in my .inputrc "\C-xr": "\C-a\C-r\C-y" and it works very nice! Thanks for this answer.

Save four strikes:

Avoid a second Ctrl-R by adding to your .bashrc (or to your .inputrc if you prefer):

bind '"\er":"\C-a\C-r\C-y\C-r"' # alt-r = ctr-a ctr-r ctr-y ctr-r

This will map ALT-R to CTR-A CTR-R CTR-Y CTR-R


  • ALT-R: the binding key. Another good option is \C-xr (CTR-X CTR-R)
  • CTR-A: Go to the begin of the line (memorizing what is written)
  • CTR-R: Start the reverse search
  • CTR-Y: Paste what CTR-A memorized as part of the search
  • CTR-R: Triggers the reverse search with the characters so far

    It still not clear to me why C-y pastes the command onto the search field (C-a is not supposed to be a "copy" command, is it?) and why C-w pastes only the first word.

  • yes, C-a not only moves, but memorize (copy) the content moved over.

  • I can't confirm that behavior (just try C-a C-y), I think it's more likely that C-r that has some special cases built in, but I don't know where they're documented.
