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

    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.

  6. 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

  8. 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”.

  9. 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?
