I am searching a dhcpd.conf to find the hardware ethernet match, then once the match is found delete just the line above it. For example:
testmachine.example {
hardware ethernet 00:00:00:00:00:00;
fixed address 192.168.1.100;
next-server 192.168.1.101;
filename "linux-install/pxelinux.0";
}
I would like to use sed to remove "testmachine.example {".
I was going to create a two step process by removing the line above the harware ethernet match. Then remove the hardware ethernet match through }. However, if someone knows how to find the harware ethernet match and remove the whole block, I would be very appreciative.
There are multiple fixed addresses in this file, so it can only remove this block based on the hardware ethernet match.
