[R-SIG-Mac] How can I find the "sh" application used by "R CMD check" on a Mac?

       How can I find the "sh" application used by "R CMD check" on a Mac?


       I need to know to be able to add it to the "Application Access" 
list maintained by the "Anti-Ransomware" feature of my Bitdefender 
Antivirus for Mac.  With that feature on, "R CMD check Ecfun" stopped 
with the following:


             checking whether package ‘Ecfun’ can be installed ...sh: 
... Permission denied


       When I saw that, I also got a popup from Bitdefender that would 
only allow me to allow this once but not permanently.  To allow it 
permanently, I need to know where it is on my hard drive.


       Thanks,
