I can't find any info regarding this in the man-pages. How would one go about only printing the gateway using traceroute?

@RuiFRibeiro Basically I'm looking for a way to use traceroute to only print one line. That line being the one containing the gateway information, nothing else.

anything against netstat -nr? I think what you want with traceroute can be done, will check it out and will come back.

@RuiFRibeiro I appreciate your help. Nothing against netstat -nr. It's only that it's a school assignment that requires me to use traceroute. I've read the man-pages but haven't found a flag that does what I want, apparently it is possible though.

You should read about e.g.grep,sedandawkand how they can be used to cut out lines fromtraceroute's output.

With traceroute you've to enter maximum hop as 1 using m1 option as follows.
traceroute -m1 google.com
According to basic rules of computer network Gateway and host must be connected to same NIC of router. Otherwise Data Link Layer will unable to deliver packets from hosts to Gateway. So it's hop should be 1.
So by setting maximum hop as one and tracing any host will prit Gateway only.
