Thank you so much for this!!!

From relatively barebones Termux, needed to pkg install which time ldd tree before your script worked.

Also might help others that after this script was successful, I had to restart session to get bun in my path. And in order for bun install to work on my prior bun project, I had to use --backend-copyfile as per this comment
