I've many files in a directories structure. I want to extract some string (namely urls) by using a regexp, from those files.

I've tried this :

find . -path "alder/ * / * .html" -print | xargs sed -n "/http://[^'"]/p" > urls.txt

... but it does not work as expected. The 'find' part works ok, the 'xargs' one, ok but the 'sed' one, no. All I get in urls.txt is the concatenation of all files.

Tricky. I'd be grateful for any help.
