Shell Script to Rename Folder and Create New Folder

I think I've got the bones. Basically a sh that mv assets assets2 then mkdir assets. Run on a launchd Day1, Hour1, Min1 (every month on the first at 1?).

Question now is I would like to incorporate some level of, simple, logging of this script just so I can see when it ran, what it ran, etc. But I have 0 experience with logging, could use some help there.

Ughhhh. I stand corrected. When I manually invoke this in terminal it works fine but when invoked by launchd I get 'mv rename operation not permitted' in stdout... I've tried giving Terminal Full Disk Access and now trying mv command with sudo.
