Hey guys,
i have written the folowing grep command to find an ip address from various files and now i have to find the reverse DNS for it.
I wanted to do it via nslookup or host
does someone have any clue about how to do it?
what i tried was
grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' Times.txt || nslookup ip
but it doesnt give any output to me?
i have used piping here...is it not valid?
