This machine is a server without DE, just command line and I didn't 
configure mail client so maybe I should use something like ssmtp.

I need to understand "just" if the upload job is finished and, I think, 
the best way is to read the log file so I should write a code like:

"if there's a line with the same date of the machine than send email 
with ok else send an email with failed"

I do just an upload every day, from monday to friday so I don't have in 
the same day other lines.

I'm reading it! :)
