Hmm, I thought for a minute that I understood what you meant, but maybe 
not. Well, actually, I think I understand what you mean (maybe?), but 
I'm not sure how that would translate to code.

I changed the code to this:

------------------------------------------------------------------------
-----------------------------------------------------
FILE* pipe = NULL;
char* args[7];
flags = kAuthorizationFlagDefaults;

args[0] = "/bin/rm";
args[1] = "-rf";
args[2] = "/System/Library/Caches/com.apple.ATS.System*.fcache";
args[3] = "/System/Library/Caches/com.apple.ATSServer.FODB_*System";
args[4] = "/System/Library/Caches/fontTablesAnnex*";
args[5] = "/Library/Caches/com.apple.ATS/";
args[6] = NULL;


status = 
AuthorizationExecuteWithPrivileges(authRef,"/bin/sh",flags,args,&pipe);

------------------------------------------------------------------------
-----------------------------------------------------

But receive the following error:
   /bin/rm: /bin/rm: cannot execute binary file

I guess what I was thinking is that I'd be running the rm command from 
within the shell, or is that not what you meant? Or that's what you 
meant, but not what my code means? :-)

Thanks for your help
