I've had the same password on linkedin for as long as I remember and neither the full hash nor the zero prefix edited was found in the dump.

Simple line used in OS X terminal:

grep -e "`echo -n "your pass" | openssl sha1`" combo_not.txt

May want to grab the last characters as the cracked passes have 00000 at the beginning:

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).
