You've misunderstood how the plugins work.

The return value (0, 1, 2) is not meant to be printed to stdout,
but instead returned as the 'exit code' of the program or script.
In PERL, you can use 'exit 1;' to return such a code.  For testing,
you can use (under a bourne-type shell) use "echo $?" to check the
return value of the previous command:

$ perl -e 'exit 5;'
$ echo $?
5

Also, Nagios will only use the first line of a plugin's output,
so you'll need to work out how to refactor the status into a
single line of output.
