Setup issue on Mac Catalina

[CreamyKnees]

Whenever i try to run the Nand to Tetris files through the terminal i am met with the permission denied message every time. i have updated my JDK the latest version and allowed both terminal and Bash full disk access. Following each step in the Mac installation guide still leads me to the same conclusion.
any help would be greatly appreciated, Thank you.

thanks. i had checked this post and, although, it was a similar problem the fix was a little different for me.
for future reference if anyone has an identical issue i made sure to set the correct privacy settings, then just opened my terminal and entered:
chmod 755 YourScriptName.sh
for each of the tools and resolved the issue, so i could continue to open the programs as normal.
