ventura / full disk access / bash

I wrote a shell script (bash) that launchd executes when a filesystem is mounted. The problem is that simple commands in the shell script fail with the error message 'operation not permitted'. A simple example is 'mkdir'. If I reduce my script to ...

| #!/bin/bash

| mkdir /Volumes/Media/directoryName

| exit

... my error log shows mkdir failed ... "operation not permitted"

• OS: Ventura 13.1
• I have granted Full Disk Access to 'Terminal' and the fully qualified path to the shell script
• The mounted directory has write permission granted (sudo chmod -R a+w /Volumes/Media)

• I have not been able to use the GUI to grant full disk access to bash. (If I use the '+' in the GUI then navigate to "Macintosh HD", the /bin directory is not shown.

My script works from the command line and launchd was able to run it before I upgraded to Ventura.

Please help --

P.S. I would prefer to use ksh over bash. The abbreviated script shown above uses bash just so I can show what the error is not. The complete script (not shown) is written for ksh and, as I said, works fine. If you can show me how to grant full disk access to ksh, (and full disk access is the underlying problem) please do so.

Thank you --
