Extracting urls from curl output
Hello.

I use curl to fetch a website, then, I want to extract the URLs from this curls output.

I tried both sed and grep, but couldnt figure it out.

Ive tried :
Code:
sed -n 's/href="\([^"]*\).*/\1/p' results.txt

and grep -o

Code:
grep -o '<a href="http://[a-z]*.[a-z]*.[a-z]*/[a-z]*">' results.txt

.

What pattern shall I use and whats wrong with mine ?


EDIT:

Added some of the data I use

EDIT 2:
Removed the data sample, because it ruines the thread width, but just curl whatever website, and use that output as data.
