I need to make sure that 7 lines of code exist in every instance of snmpd.conf in our network. I do not want to overwite the files as some customers have added special things to this file for their own monitoring. On top of that I don't want to just willy nilly append the 7 lines in case the data already exists in the file. I need to check the file first for the existence of this code, if so leave it alone if it doesn't exist then it needs to be appended to the file.
Definitely a proper program needed in that case.
I'd recommend Perl, easy to write, fast running and has modules avail for dealing with networking, snmp etc.
In fact, that's exactly the sort of thing it was originally designed to handle, way back when.
