Hey Look, This isn't a Language Shitpost

Hello /proggles/. In the midst of all of this "faggotry," I propose a thread about actual programming.

Suppose you have a sort of root directory with a large number of subdirectories all containing a large number of files. The files all exist in ranges of size from a few kilobytes to several gigabytes. Given an input file, let's conduct a quick method for searching our root directory and its subdirectories for copies of the input file.

I've thought of a fairly decent algorithm that I will share if anyone here is interested enough to share their own.

>>9
Actually, this is slow compared to the solution I had in mind. Using md5 hashing requires a hashing computation to occur on the entirety of all n files. In essence, you are recommending the solution proposed in >>4.

But nice try. As said before, this is a feasible, but not optimal solution. If I have to read every bit of every file, I'd hardly consider it fast.

Also, English or pseudocode please. It is rare to find somebody who speaks Bash natively.
