  • The ebay URL is the search query copied from the browser (here searching for bed stuff). The regex is for crap that should not be shown. Important is "Pickup only", which filters away all the things that cannot be shipped (a filter that cannot be done on Ebay's webpage). It will output the title and url for all matching items, for all pages of the search result. It also works for the German Ebay. Show Sample Output

  • This logs the titles of the active windows, thus you can monitor what you have done during which times. (it is not hard to also log the executable name, but then it is gets too long) Show Sample Output

  • Updated to the new version of the MW webpage (seems MW does not use cougar anymore, so the other commands do not work nowadays), and using Xidel to parse the page with a html parser instead regex. Example usage: pronounce onomatopoetic I'm not sure how well Xidel works with binary streams (although it seems to work great in tests), so using wget to download the actual wav file might be safer, i.e.: pronounce(){ wget -qO- $(xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1]/@src') | aplay -q;} Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net
