Mmh, getting back to the topic of comparing files, I realize that the Compare... commands have smartness built in (they check file size first, and then a small chunk at the beginning and end of the file before going "brute force" bit-per-bit). What if such smartness was available via a scripting function too? Then multiple files could be compared at once, it would be trivial for a scripter setting up a foreach loop that aborts as soon as one file looks different from the other scanned.
AFAICS, there's not a filecompare() function. And comparing hashes is not exactly the same thing, due to (un/likely) collisions.

The code is already there (since 20110321
) but I had no time to dcoument it.
Code: Select all
comparefiles(file1, file2, [hash])
I look over it for glitches now...
