Hello, i want to extract a word with a regular expressions from a line of text. Here is what i currently have: grep -c -E 'Interesting ports on [a-zA-Z0-9-.]+ \((.+)\)' This will print lines (from nmap), but i need only the 1st match in parentheses, which is the IP in this case. What programm would i use to print what grep sees as \1, instead of the whole line? Thanx
