You want to use cron on Linux for applications that need to run at specific
scheduled times or intervals.

So you could write a script that looked something like this to do a one-shot
ftp and then have cron run this script every x minutes:

#!/bin/sh
test -f /trigger/file && ftp <</ftp/command/file

Probably adding some sanity checks to make sure the ftp completed successfully
would be a good idea.  ;-)
