A Random file picker made for /u/Sr_Navarre for request https://www.reddit.com/r/programmingrequests/comments/ahyb10/random_file_picker_for_mac_that_supports/

randomizer.sh

#!/bin/bash
#This file will take two inputs. One origin directory with N subfolders
#Another Directory which to post the Copied files to
#a Count as a number
#Will output in Target Directory a random selection of files.

#you may have to give permissions to this file to work via `chmod 755 randomizer.sh`
#You can execute the script by ./randomizer.sh '/home/me/Desktop/Files' '/home/me/Desktop/Destination' 5 2>/dev/null
#You will see some printed output. You can open the directory and the files will be present.
#If you specifiy a higher count than files that exist you will have to force kill the script.
