Krawler

Simple little command-line web crawler. Use it to find 404's or 500's on your site. I use it to warm caches. Multi-threaded enabled for faster crawling.

Installation

Install:

gem install krawler

Usage

From the command line:

$ krawl http://localhost:3000/

Options:

-e, --exclude regex              Exclude matching paths
-s, --sub-restrict               Restrict to sub paths of base url
-c, --concurrent count           Crawl with count number of concurrent connections
-r, --randomize                  Randomize crawl path

Examples:

Restrict crawling to sub-paths of /public

$ krawl http://localhost:3000/public -s

Restrict crawling to paths that do not match /^\/api\//

$ krawl http://localhost:3000/ -e "^\/api\/"

Crawl with 4 current threaded crawlers. Make sure your server is capable of handling concurrent requests.

$ krawl http://production.server -c 4

Randomize the crawl path. Helpful when you have a lot of links and get bored watching the same crawl path over and over.

$ krawl http://localhost:3000/ -r
