My business purpose is monitoring the remote file system on Linux and if there is any new, SFTP to another machine and delete them.

But the thing is I can't install any libraries on remote machine. So what I am thinking of is sending interval SSH command polling to remote machine.

And here it is my question.

1. Interval polling is implementable? Or if there is any better idea, please let me know!
2. What kind of SSH command should I use to monitor the remote machine?

Sorry if I neglect the conduct. Thanks.
