I will give anyone 250 points if they provide a solution that removes a line from a file and can provide an explanation of the source. I just started learning PERL and am totally lost.
I would like to be able to execute ./removeA.sh 1.domain.com A 127.0.0.1 and be able to remove line one.
1.domain.com. IN A 127.0.0.1
2.domain.com. IN A 127.0.0.1
3.domain.com. IN A 127.0.0.1
4.domain.com. IN A 127.0.0.1
