Denis,
I still failed to write to the poll_result.txt file and I noticed
there's a slight difference between this file's access attributes
compared to a similar target text file with a similar script and
process. The other target text file has rwxrwxrwx attributes while
this one has rwrwrw attributes. I thought the global writable would
suffice but it seems I was incorrect. My ftp client failed to do
chmod 755 to the global x (execute) attribute to the file.
Thanks though.
Don
