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?

SLIST(1)							       slist								  SLIST(1)

NAME
slist - Lists available NetWare Servers SYNOPSIS
slist [ pattern ] DESCRIPTION
slist lists all NetWare Servers available in your network. If slist does not print to a tty, the decorative header line is not printed, so that you can count the servers on your network by doing slist | wc -l OPTIONS
pattern pattern is used to list only servers whose names match the specified pattern. For a server to be listed, the pattern must match the full server name. You can use wildcards for the pattern, but you must protect these wildcards from any command line expansion by quoting. Case doesn't matter. EXAMPLE
slist "I*" or slist "i*" List all available Netware servers on your Network, that begin with an "I". SEE ALSO
ncpmount(8), ncpumount(8), pqlist(1), nprint(1) CREDITS
slist was written by Volker Lendecke (lendecke@math.uni-goettingen.de) BUGS
slist works only in IPX environment, as it uses SAP to find first server and then Bindery to get list of servers. slist 01/07/1996 SLIST(1)
