I have a issue, I am generating millions of addresses with vanitygen, I have 55 thousand bitcoin addresses that I have saved in my computer and I want all my vanity addresses been checked if collide with any of my 55k addresses.
for example:
money.txt is my vanitygen addresses
cash.txt is the addresses I have with bitcoins in it
I need all addresses in money.txt compare with all addresses in cash,txt to see if found any collision.
How can I do it?
I liked xhomerx10s answer the best, but...
Use comm or grep or fgrep.
E.g something like:
grep -F -x -f file1 file2
Sort cash.txt before you save it.
Write a simple computer program that performs something like a
binary search of the sorted data.
It will be faster, and more customizable than grep.
