A Cool Piece of Code

Can any of you figure out what this single line of code does?

for vari in `cat file1`; do curl $vari | grep "comments</a>"| cut -b 213- | awk '{s+=$1} END {print "Total: " s}' >> file2; done

Hint - file1 looks like this:

http://becauseichooseto.blogspot.com/
http://enterthenerd.blogspot.com/
http://randomness976.blogspot.com/

and file2 looks like this:

Total: 71
Total: 96
Total: 20

Well, anybody? Come on Cody, you should be able to get this.
