AWK error when running rsdns-dc

[ianb445]

Hi,

A big thanks for the software, has made updating RS records a breeze. I recently upgraded to Ubuntu 22.04 and found the Dynamic DNS update functionality to be failing with an error.

awk: cmd. line:1: warning: regexp escape sequence `"' is not a known regexp operator

I am able to create DNS records, but when I try to run the -dc.sh I receive this error.

Thanks

Ian

There is an escaped " that needs to not be escaped. See pull request #49
