Trying to replace a DNSmasq entry that has quotes in the value

[Ronv42]

Today I almost completely finishined converting the custom DNSmasq configuration files to using Merlin's postconf script option. This will allow me to continue to use the web user interface while maintaining my customizations.

One thing I am having an issue with is this option:

dhcp-option=lan,252,"\n"

It's in double quotes and the pc_replace directive doesn't seem to work on the \n or the double quotes. Here is what I am trying to replace it with:

dhcp-option=lan,252,http://192.168.10.254/wpad.dat

Any suggestion on coding the pc_replace command? I have tried but my coding of expressions leave much to be desired..

Try using this instead:

sed -i 's|^dhcp-option=lan,252.*|dhcp-option=lan,252,http://192.168.10.254/wpad.dat|' $CONFIG

sed -i 's|^dhcp-option=lan,252.*|dhcp-option=lan,252,http://192.168.10.254/wpad.dat|' $CONFIG

Thank you. I see what you did...beginning line with the string of the option with wildcard at the end....
