Thanks for the info.
I appreciate your efforts. An introduction and little bit of explanation on every step would have been even more helpful.
I have a question,
Won't lt_data get refreshed after every FTP_COMMAND call? If that is a yes,then are we trying to get the log for only the final command here?
There is the exit in the loop after the connect. So the first file that fails stops the program and returns the message.
You could monitor for every command to fail and exit. I'll see if I can edit that in...

Good Article Neal Wilhite
I hope to get back to it and give better documentation later... As previously asked.
useful article...thanks for info.... 🙂
