EAV script to monitor a FTP PUT process

I need help writing an EAV script to monitor a FTP PUT process on an Active FTP server. This will mimic the customer's interaction withe FTP server, that is why it must be a PUT command.

 

I can do this manually with cURL:

 

curl -T /root/ftp_put.txt ftp://: -u :-v -P -

 

Trouble is, how do I validate the "226 transfer complete" message to mark the Pool Member up?
