I'm not sure if the title of the thread captures what I'm trying to do, but here goes anyway:

I have a script to flush a file that I need to run on ~20 linux boxes. What I'd like to be able to do is have a single script that I run from a central machine that can execute the flush script on each of the servers.

It can't be done as a cron job, and it's in response to an alert I receive. The script itself won't reside on any of the servers ideally, as I'd like to be able to change it on the fly in response to the alert.

I'm absolutely certain that this is a simple thing to do and I'm just being a tard

I'd be very grateful if anyone could help.
