That’s all. I just found this in a random script. Generates a random UUID every time it’s called. I didn’t know.
Of course I can also use uuidgen or pipe /dev/(u)random into something to get a random alphanumeric string - but this is built right into the kernel!
In /proc/sys/kernel/random/, there’s also boot_id which seems to do the same, and some tweakable parameters.

Yeah but please don’t actually use this. Use a proper UUID library that works cross-platform and lets you choose the UUID type and can be seeded etc.
I’ve used this in some bash scripts, very useful!
This is awesome. Thank you
Works in Termux on Android
