This grep regex would be very useful later if you don't mind sharing it.
This is the most complete list I've seen so far:I actually can 
I found this regexp on Stackoverflow:
I have compiled these from various sources and use them to automatically set my blockchain explorer options based on user input, and also keep them at my .zshrc : I found this regexp on Stackoverflow:Code:
egrep --regexp="^[13][a-km-zA-HJ-NP-Z1-9]{25,34}$" filename
With some slight changes it stops matching parts of Eth-addresses:Code:
egrep -w --regexp="[13][a-km-zA-HJ-NP-Z1-9]{25,34}" *

Flag -w is 'word bondary' and can also be set within the regex with '\b' at the ends.

As I understand I could make one file with addresses that have balance, second file with private keys and then compare these files.
I would get 2 lists of addresses: one with all funded addresses, and one list with the addresses you want to compare. If you find a match, you search your list for the private key for that address.I'd start with this:
On Linux, use this to find matching addresses (after extrating the compressed .gz file of course):
Code:
comm -12 Bitcoin_addresses_LATEST.txt <(cat mylist.txt | sort | uniq)
- Bitcoin_addresses_LATEST.txt: the extracted latest version downloaded from addresses.loyce.club.
- mylist.txt: your own list of addresses, one address per line.
Code:
comm -12 Bitcoin_addresses_LATEST.txt <(cat mylist.txt | fromdos | sort | uniq)
