test your contacts against the gmail password compilation

gmail-test.sh

#!bin/bash

echo "Export your Gmail contacts as a CSV, name it contacts.csv, put it in this directory, press Enter"
read foo

wget --referer=https://forum.btcsec.com  https://forum.btcsec.com/uploads/manual_09_2014/google_5000000.7z

echo "I haven't worked out a way to unzip .7z files from a cli yet... patches welcome"
echo "Press enter when you've unzipped the file"
read foo

sort google_5000000.txt -o google_5000000.txt 
comm -12 <(egrep -o "\b[a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z0-9.-]+\b" contacts.csv | sort) > matches.txt
cat matches.txt

via @spicydonuts On a Mac $ brew install p7zip

If you have 7zip installed, 7z e filename.7z

I get the following error:

comm: missing operand after ‘/dev/fd/63’

shouldn't your comm command take in google_5000000.txt as an input?

I did this too: https://github.com/rodrigorega/wordlist_compare

I like your approach :)
