That never occurred to me. Thanks, it works very well. However, the output is:

Code:
http://ADDRESS_1/?click=5BBB08\
http://ADDRESS_2/?click=5BBB08\
http://ADDRESS_3/?click=5BBB08\
http://ADDRESS_4/?click=5BBB08\
http://ADDRESS_5/?click=5BBB08\
http://ADDRESS_6/?click=5BBB08\
http://ADDRESS_7/?click=5BBB08\
http://ADDRESS_6/?click=5BBB08\
http://ADDRESS_7/?click=5BBB08\

Now I only need to get rid of the duplicate entries.

I did try sort -u and got what I wanted.

So final:

Code:
awk '/http/' RS=\" infile | sort -u

Wow, that's neat.

Combining these two ideas into one which checks duplicates and doesn't need grep:

Code:
find . -name "*php*" -or -name "*htm*" |
        xargs awk -F\" -v RS='<' '/^iframe src=/ { if(!X[$2]++) print $2 }'
