Welcome to the Linux Foundation Forum!

Confused by some possible answers in the LFCS questions

I'd like to ask about what is allowed in the LFCS exam.

In the first question of the sample LFCS exam http://puu.sh/FAsSp/925377e255.png , am I allowed to install nano to make the required changes?

In the second question http://puu.sh/FAsUm/cc08253f73.png , can i just manually check the IP and make the script paste it (echo "192.172.14.1")? If not, would an "ip r/route" suffice or do I have to extract only the IP address with awk/sed. I really want to keep going but I can't because there's a lot of confusion about how I'm supposed to solve it.

Thanks ahead!

    Thanks for the response, where can I ask about the LFCS? I couldn't seem to find it. I'm trying to get an answer for these for days(

    I wrote them an email a few days ago. Do you know how long it takes them to respond?

    this is not an authoritative answer, but I'm pretty sure you can install packages from the normal system (e.g., apt-get or yum install nano) and nano should be installed by default on any distribution I've ever seen anyway. Certainly vi would be there too.

    Thank you, I really appreciate it. Do you happen to know their expectations for my second question? i can rephrase if I the wording was confusing

  • Hi @rogersjoshmac ,

    I think that a question like this implies to extract/obtain the IP with a command or commands. I don't think it's supposed to be manually entered, because in that case it doesn't make any sense as a script.

    So, I think ant scripting question like that -at least another thing is specified- will expect a command to get the information. In this case it would be something like this:

    [email protected]:~$ ip route show
    default via 192.168.1.1 dev wlo1 proto dhcp metric 600
    169.254.0.0/16 dev wlo1 scope link metric 1000
    172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown
    172.18.0.0/16 dev br-520cd078840f proto kernel scope link src 172.18.0.1 linkdown
    172.19.0.0/16 dev br-063cb39044ea proto kernel scope link src 172.19.0.1 linkdown
    192.168.1.0/24 dev wlo1 proto kernel scope link src 192.168.1.10 metric 600

    [email protected]:~$ ip route show | grep default | awk '{print $3}'
    192.168.1.1

    So, the command ==> ip route show | grep default | awk '{print $3}' may go in the second output line. I bet there would be better ways to get this done, this is just one way.

    Regards,
    Luis.
