Simple line used in OS X terminal:
grep -e "`echo -n "your pass" | openssl sha1`" combo_not.txt
i=`echo -n 'mypass' |openssl sha1 |echo ${i:14}`; grep $i combo_not.txt
This yielded success on some known passwords and a bunch of obvious passwords. Not mine, but I assume this dump is a list of the passwords they've cracked so far (i.e., even if your password isn't on this list - change it).
