    Good concise tutorial, thanks.

    Yeah, except ifconfig is going away for the more feature-complete ip command. ip pretty much has the same syntax setup as git, but can let you do anything and everything you’d want, from basic interface up/down commands, to configuring vlans and bridged connections that you’d normally only be able to do on an enterprise-grade router.

    “54. Command: vi/emac/nano”

    First of all, it is spelled “emacs” NOT “emac”. Secondly, where is your explanation of the editor?

    Unfortunately, all your explanations are too simplified to be usefull.

    “man” should be the the first command explained in the first section, not in the second!

  8. David Dreggors says:

    I notice you explain deprecated commands like ifconfig and nslookup. you should at least cover their replacement comnands (ip, ss, host, etc..) as well.

    They are either easier to use or in some cases the same flags are used and they do a better job of output.

    ifconfig -> ip addr show (or shorthand “ip a sh”)
    nslookup myhost -> host myhost
    netstat -anp -> ss -anp

    There are way more but you get the idea. :-)

  9. Rick says:

    There seems to be something missing from 59. Command: paste

    I finally did a paste file1 file2>file3
    and I got the desired result.

    I didn’t see that explanation in this tutorial.

    Just be careful that you don’t issue “ifconfig eth0 down” over a SSH connection to a remote box. You might end up needing 2hr of driving just to issue one command from the console. Not that I’ve ever done this. :-)

    Also, a couple typos:
    s/Query Start of Autory/Query Start of Authority/
    s@Command: vi/emac/nano@Command: vi/emacs/nano@
