When importing services.cfg from nagios2 to nagios3 with Centreon there are few parameters that must exist,
one of them is service_description. In a project I had to import almost 4 thousand services and many did not have
a service_description so I wrote this perl script to parse the services.cfg and get the use info parse it and set as a service_description, it can also be used for other means, like changing just a specific service…
The script use a nice concept called Finite State Machine
version 6, generate new services.cfg creating service_description, download here
version 7, looks up for a specific service or host and changes itm download here

I am in a project to import over 600 servers from old nagios 2.0 to nagios 3.0 / Centreon.
So the sysadmins here do not put the address field inside the hosts.cfg, so I either ping 500 servers copy
and paste the IP, or I write a script that does it to me.
Here is the  perl script to get IP address from hostnames

Getting email from the command line was always something I wanted, also to be able to filter what I get.
This great tool is something like fetchmail but better, thanks to Charles Cazabon who wrote this amazing tool in python. Here is more info http://pyropus.ca/software/getmail/
Later I could even have it scripted, if I need to search my emails, it should download the mailbox (without any attachments) and then search for a string within all emails. Well its not all done, but I believe I found the correct tools for it. Hope to come up with nice script in the future.
