Do you have any links to resources you used to build it or better yet a link to your implementation?<p>I&#x27;ve been pretty happy with my bash history solution, but thinking about the return value, one big thing I think would be handy would be to have a default filter for searches that removes commands that returned an error code.  They might be handy to see every once in a while, but for the most part, I wouldn&#x27;t want to re-run one of them.
