Question : Help creating small shell script to manipulate text file data.

Ok so this is the .inf file I want the shell script to manipulate.

An example of what I want it to do....

4 Staticaly defined variables.
$HOSTNAME ex. test01 --> ComputerName
$IP ex. 10.2.0.10 ---> IPAddress
$GW ex .10.2.0.1 -----> DefaultGateway
$MASK ex. 255.255.255.0 ----> SubnetMask
$DNS1 ex. 10.2.0.15
$DNS2 ex. 10.2.0.16 --> Both need to go to DNSServerSearchOrder (comma seperated)

The idea each of these would be blank (below). And the shell script would search for them and fill them in with the value from the variables.

ComputerName=
IPAddress=
SubnetMask=
DNSServerSearchOrder=
DefaultGateway=

Thanks for any help, this would be a bash shell.
