How can FTP servers be configured to trigger scripts upon file upload, and is this a viable solution for initiating scripts on a different server?

To trigger scripts upon file upload on an FTP server, you can use the inotify-tools package to monitor the upload directory for new files and then execute a script when a new file is detected. This can be a viable solution for initiating scripts on a different server by having the script communicate with the other server through an API or by triggering a webhook. 

<?php
$dir = '/path/to/upload/directory';
$cmd = "inotifywait -m -r -e create $dir | while read path action file; do /path/to/script.sh $file; done";
exec($cmd);
?>
