I have several Pis around displaying reports, which are really just php files and a web browser. They are on a 5 minute refreshing loop I set up with a script, and all works fine and dandy, but sometimes I may need to manually refresh them. I set up an alias using the "xdotool" to basically hit the F5 key, but with currently 3 displays, and ~7 more in the future, I don't want to have to do this to each one at a time. So I was looking in to doing it with SSH's ability to submit remote commands without fully logging in.
My idea was to create a small script that will systematically go through each Pi and submit my refresh command automatically, but the exact way to do this alludes me. Most pages around the net are written in technical jargon that just confuses me, so laymans terms are appreciated.
