Manipulating syslog-ng.conf via script

[cmschube]

Hey All -

I want to be able to append text to the syslog-ng.conf based on some input from the user.. Basically I'm going to ask for the name of the syslog server and based on that point the syslog-ng.conf to throw all the d_auth information to the syslog server..

basically change

destination d_auth { file("/var/log/secure"); };

to

destination d_auth { file("/var/log/secure"); udp("servername" port(514); };

based on a READ variable

I've checked around about using sed, but I can't find any option to append directly after matching a search string, it just seems to want to append a new line..

I've found that syslog-ng will support two d_auth lines in the config file, but I'm still interested to know how to do something like this.

Any help is appreciated..

Thanks,

Chris
