Sending emails from within a script
ScriptFTP has been designed for unattended operation and usually you will know what has happened during a script run just by taking a look at the ScriptFTP window. Additionally, you may log a script’s output messages to a text file and even have it send emails to you which contain information about the run. This section is dedicated to this topic.
In ScriptFTP there is no built-in command for sending emails because it is not needed. We will rather use the EXEC command to call an external command-line program that will send the email. The following examples use Blat, a free and tremendously useful command-line mail program for all kinds of batch jobs. However, you can use any other mail program just by adjusting the EXEC call.
The following example script will send an email if it cannot connect to the FTP server or if the file synchronization fails. Note that we first setup the way how Blat will be invoked. We construct two different commands for calling Blat, one for each type of error, since the user should tell from the email what happened exactly and not be confused by a generic error message.
