True, but that is a web browser solution, not something that could, for example, be scripted (well, not easily or realistically for this sort of task). Also, appending a "+" I believe does the same thing, and is easier to type. http://goo.gl/ylUAd+ Either way, that redirects to a URL in the form <https://goo.gl/#analytics/goo.gl/<shortcode>/all_time> So that could probably be scraped as well if you really wanted to scrape a web page. Still, this isn't a viable solution for spam checking, though I suspect there is a low-cost "get redirect URI" library that would have less overhead than curl and could grab the Location from the 301 (or 302?) redirect, much like curl can do with a -I or -i flags. Regardless, Reindl was clearly wrong that checking the shortner targets would require loading the target URL. Maybe curl ain't so bad? # time curl -sI http://goo.gl/ylUAd | grep -o "http.*" http://www.hollywoodreporter.com/thr-esq/donald-trump-threatens-sue-macy-422135 real 0m0.098s user 0m0.000s sys 0m0.008s I threw this together in a few minutes and it seems to work: --- #!/bin/bash if [ "$1" = "" ]; then echo "usage $0 <URL>" exit 1 else URL="$1" fi myInfo=$(curl -sI $URL | grep -o "http.*") if [ "$myInfo" = "" ]; then exit 404 else echo $myInfo fi --- # curlri www.covisp.net # This uses rewrite https://www.covisp.net/ # curlri www.google.com # No redirect, so returned 404 # curlri http://goo.gl/ylUAd # Voila! http://www.hollywoodreporter.com/thr-esq/donald-trump-threatens-sue-macy-422135 It even works for the t.co link: # curlri http://t.co/UShCXQG http://www.youtube.com/watch?v=dfJ6oCdjY9Y -- It is one thing to be mistaken; it is quite another to be willfully ignorant ~Cecil Adams
