Tech tip #4: Copy a random set of files from a directory.

More for archival purposes than anything, today I wanted to copy some songs out of my serious mess of a music "collection" onto my microSD card. I didn’t want to have to choose and I haven’t rated my songs so that wouldn’t help. Instead I wanted a random selection of songs. I’m not a bashmaster (absolutely pathetic at it, actually) but this is what I ended up using – after symlinking all of the various directories I had my files under together:

find -L /home/drive/music -type f -name "*.mp3" | sort -R | tail -n100 | while read file; do cp "$file" /media/disk/music/; done

-n100 represents how many files are going to be copied. Hope it helps somebody! Of course any improvements are welcome.
