How would I go about determining if a given folderitem is an

It depends on what you mean. Other people have said how to tell
whether the file has execute permissions set. But those can be set
for any file. If, on the other hand, you want to know how to tell
whether a file consists of executable code, then that's a little
more difficult. If the first eight bytes of the file are 'Joy!
peff', then it is probably a PEF executable. Mach-O executables
also begin with a header whose structure is documented in Apple's
Mach-O docs, but I don't know offhand an easy test for Mach-O format.
Use the "file" command line tool:
shell.Execute "file " folderitem.shellPath
If the response includes things like:
filename: Mach-O universal binary with 2 architectures
filename: Mach-O executable i386
filename: Mach-O executable ppc
filename: header for PowerPC PEF executable
It's a binary file. Combine that with the permissions bits discussed
previously and you'll have a pretty good idea of the type of file
you're dealing with.
