I am using ubuntu 14.04. Thanks! The -o option was a big part of what I was looking for. Thank you!

Currently, I'm getting
Code:

http://images.site.com/uploaded_pics/thumbs/19434.jpg

Desired result is
Code:
http://images.site.com/pic/19434-3201cd0ed412e26b2c06cf00a0803c64.jpg

Whenever I use lookbehinds I get no results at all. ex:
Code:
grep -Eo '(?<=")http.*jpg' file
grep -Eo '(?<=\")http.*jpg' file
grep -Eo "(?<!\')http.*jpg' file



I was able to get the desired result with
Code:
grep -Eo 'http\S*\/pic\S*jpg' file

I am still not sure why the lookbehinds didn't work. Please let me know if you have any insight into what I'm doing wrong and thank you so much for the help!
