GREP help: Bitcoin address/key buried as text somewhere on hdd

GREP help: Bitcoin address/key buried as text somewhere on hdd

So in a drunken moment of genius I had forgotten about, I bought some Bitcoin way back. And I buried the address and key in some file… I was being tricky lol. That likely also led me to abandon a wallet.dat completely.

I’m learning to use grep to hunt it down, but the one time I know I got it to work, it returned TONS of files.

I know the address starts with 1F or.. f .. or D.. or d, maybe E/e lol. But one of those. The original parameters from stackoverflow for finding the address are:

[^13][a-km-zA-HJ-NP-Z1-9]{25,34}$.

I’ve attempted to adjust it to remove the 3 and have been attempting to add the first letter, but I’m trying a grep search with each and as I see no results after 20-30 minutes, I just ctrl-c the thing.

I’m trying
yay

I removed the ^ and $ from the ends after when I realized that there is no reason to think it’s at the beginning or end of a line (if I properly understand what that even means).

The search area is for where I’ve recovered the files from these drives to, I’m hoping my “genius” drunken drive mapping attempts and subconscious file preservation impulse kept the file(s) from being overwritten.

Any help would be very appreciated, thank you.
