We run maintenance
We need to run maintenance on servers listed in the text files. I need to be able to have the file automatically change the text file (to a new list of servers) ever week.
The servers are in week1..., week2... and so on.
So basically my aim is to have the server rotate the list of servers going formaintenance every week.

------ Post updated at 07:49 PM ------

Code:
perl -i -pe 'BEGIN{%id=(1=>2, 2=>3, 3=>4, 4=>1)} s/week(\d)off/week$id{$1}off/g' program.sh

What is program.sh here?
