    Seems like I’ve been cut off the link to the web, my xfce and xubuntu systems just totally lost there connection? Wasn’t even hacking at the time, seems like my connection is being made really difficult!! Please can anyone help?

  2. vicky says:

    There should be more core questions, like Boot process, kernel compilation, checking and monitoring CPU, mem and network stats.

  3. Karim says:

    just for fun, using your own technics, I did a whatis on more command which displayed something like :

    # whatis more
    more (1) – file perusal filter for crt viewing
    more (1p) – display files on a page-by-page basis

    Then I applied that to your question number #7 and it showed that you’re contributing to a common misuse of the pipe among sysadmins; in other words no need to pipe cat in more or less

    no need to

    pipe cat in grep, wc, cut
    pipe find in grep
    … you get the point.

    Other than that, as someone said, your article is still useful, I think there is many levels to mastering Linux, and your article is definitely contributing to raising the level up.

    I am working as System Administrator (nix) for “AN” NGO.

  5. How is “dirs” different from “pwd” ????

    exellent site in linux

  7. Anand says:

    I loved extracting the good in the article rather than finding negative things like other did.

    Thanks Avishek

    Good article waiting for some more

  9. Todd says:

    Question #8 is for an Oracle database, not a core Linux knowledge item. Question #7 is often advised as not the best way to do it (google “useless use of cat”).

    The rest are good bash tips though, so maybe a better article title would be “8 Core Bash Interview Q&A”.

  10. Bob says:

    You should learn a bit more about things before writing these articles.
    Your “core linux” things are sometimes bash-specific.
    And you should look up what “UUOC” means and try to understand it.

    • Evil Kitten says:

      Lol yes: why pipeling if you can just do `less file_name.txt`. And as for me, I never use `more` if there is `less`.
      BTW, could I just press Tab-Tab instead of compgen?
