Say I have a folder with a few thousand documents/images...

shuf is the key thing of interest, since it'll shuffle whatever sort of list is piped into it. From there, you just have to figure out a way to get the list of files.

Obviously, works, but it's not ideal, since find is a truly awful program -- way too complex, way too finicky. grep is simpler and better, and -- in a perfectly Unix-y way -- it can be paired with ls to get the result.

ls -F | grep -v /$ | shuf -n 500

ls -F will append / to directories; this is useful since (without colors or anything fancy) directories are normally indistinguishable from regular files. The entire list of files/directories gets piped into grep, which then removes (that is, inverse searches, via -v) any line that ends with /. Note that, because of the way most Linux/Unix/whatever file systems work, a regular file can't/shouldn't contain / in its name, so we could remove the $ from the grep command it'd probably work the same.

shuf, of course, does what you'd expect: shuffles the input line-wise and then takes the first 500 lines.

parsing ls is gonna bite you in the end. find is probly way slower but it also has a -type f which is more reliable than whatever you're doing to pick non-slashhed filenames.

I owe you guys a few beers

also something for yall 'ls |' people to think about, find has a "secure" -delete command so you dont have to send a file named filename_$(rm -rf /).txt to | rm like a fucking retard.

This is to get random pics from a fap folder, isn't it?

i wish i were memeing, but no. i guess i'll explain since i'm a fucking retard and im sure there are several competent anons here. the purpose of this is to train object detection apps.my fap folder is pretty well categorized as is

So do you know where it's from or who that is?

ls -1 | shuf -n 500

don't know where they're from, but interns have annotated what im looking for. also, an image in one directory is related to an .xml annotation in another.
but what has been posted so far has been a tremendous help already!

Train one to sort new shit to your fap folder for you!

im working on something like this too kek

Never parse ls.

I remember this image from so long ago, still can't find the sauce.

If I had a crazy amount of money I would literally suffocate in female ass.

Find is not even Bash.
