I do not know bash, but I am familiar with regex in perl. I need a command like regex to find the following things within a bunch of text files:
1) domain.com without a trailing dot. So the text files should have domain.com. in them but should NOT have domain.com (without trailing dot). So I need to find any domain.com without the trailing dot.
2) I need to find any ipv6 reverse record node that is not formed correctly. If it is formed correctly it will have 16 hex digitals seperated by a dot. (ex. 22.214.171.124.0.0.0.0.0.0.0.0.0.0.0.0)
I would like to simply run grep -regex- * if possible.
