Well, to be blunt, nice try. The script is fair at best, but has lots of issues.

1. The submitted script was written in a Windows editor, and as such, has lots of ^M at the end of its lines, and so, in Linux it won't execute unless this is fixed.

2. There is a line there that sources a file called utils.sh, which wasn't submitted and if you look at some of the functions the script is using (like print_revision and support, which simply don't exist in the submitted script.

3. The grep that you are using for UPDATESTATUS, simply doesn't work, since you had it at -A 1 but 'version' doesn't exist in line 1 of that grep, for me I had to change it to something like -A 10 in order to find the 'version' and be able to grep it.

4. There is an 'if test ${ALARMVAL}', which calls for $5 ... again, which isn't being given to the script at any point... so what is $5 for/suppose to be?

---
Having said all that, the script does give you a head start if you are going to need it and if you have time to edit it to match and work for you.
