Sure, but reverse-search-history is probably what you want: C-r<string> ...recalls the most recently occuring line matching <string>. Repeating the C-r (that's <ctrl>-r BTW) finds the next prior match. Very useful that. I'd actually used bash for a few years before having it pointed out to me. Peace. -- Karsten M.
