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?

MEMCP(1)							   libmemcached 							  MEMCP(1)

NAME

       memcp - libmemcached Documentation

       Copies files to a collection of memcached servers

SYNOPSIS

       memcp [options] [file] [server]

DESCRIPTION

       memcp copies one or more files into memcached(1) servers.  It is similar to the standard UNIX cp(1) command.

       The key names will be the names of the files, without any directory path.

OPTIONS

       You can specify servers via the option:

       --servers

       or via the environment variable:

       `MEMCACHED_SERVERS`

       If you do not specify either these, the final value in the command line list is the name of a server(s).

       For a full list of operations run the tool with the option:

       --help
