You can create a temporary directory by using mktemp. This is more simple and robust against name collisions.

Got an error. Tried a simple GitHub app.

@voltechs I've updated the script, try it. Never tested on MacOS, which you seem to be using. I've used this tr man page: https://ss64.com/osx/tr.html — hope it's correct.

Ah, I see what you're trying to do here (I didn't spend a lot of time digging into it earlier). the -C doesn't help on mac, keep it as -dc. Here's a snippet that works for me. Maybe it works for you too and or there's a middle ground?

suf=$(cat /dev/urandom | LC_CTYPE=C tr -dc 'a-z0-9' | fold -w 8 | head -n 1)
