Thanks for your help but I only seem to be able to check whether or not the
user running the script has "rwx" permissions.  I am looking to find the
permissions for owner/group/other, preferably in numeric mode. Is there a
function that allows this that I just haven't found? Are you aware of any
add-on modules that might do this... You plug in a file and it spits out the
file's permissions.

I really do appreciate your help.
