    on questions: Which of these commands searches for a package name containing a specific command called restorecon?

    I believe that there aren’t any yum whatprovide option

  2. timlee says:

    Correct me if I am wrong. Based on this question it should be -d instead of -b?

    Which of these commands creates a user member of the supplementary group called team with a home directory called /opt/user?

    Answer provided is:
    useradd -aG -b /opt user

    However from man,
    -b, –base-dir BASE_DIR base directory for the home directory of the
    new account
    -d, –home-dir HOME_DIR home directory of the new account

      I think both options can be used.

      • matt says:

        I actually had the same questions so I looked into it. In the options given by the questions the -d would not work. I’m pretty sure when you use -d you have to give the full path to the home directory so it would need to be something like:

        useradd -G team user -d /opt/user

        The -b option appends the username to the path in the command. So out of the options given only the -b option will correctly set the home directory to /opt/user.

        • CertDepot says:

          Personally, I find the useradd man page about the -b and -d options not very clear.
          Initially I chose the -b option. Recently, I reread the man page and was not so sure …

    Hi,
    Can you please explain for me. I can’t understand this.
    $ echo [10-19].txt
    0.txt 9.txt

    Ref: http://unix.stackexchange.com/questions/68941/working-of-rm-ls-with-0-9

    Thank You

    • CertDepot says:

      Create a new directory and go to it: # mkdir test; cd test
      Create the 4 following files: # touch 0.txt 1.txt 2.txt 3.txt
      List the new created files: # ls -> 0.txt 1.txt 2.txt 3.txt
      Now, you can use a filter to select some of these files (here [0-2] specifies a range): # echo [0-2].txt -> 0.txt 1.txt 2.txt
      Here, we select only 2 files: # echo [03].txt -> 0.txt 3.txt
      The expression echo [10-19].txt is a mistake: it should be written echo [019].txt
      [10] represents the characters 1 and 0, [0-1] means [01] because there isn’t any other character between 0 and 1.
      I hope it’s clearer. Also, don’t spend too much time on this, this is not critical!

    Objective: “Change of root password without knowing it”
    I wonder how they will ask this question. Will they ask to setup a lab? In the case if they won’t provide root password and ask us to create one means if I fail to generate one, exam is gone?

    for the question: Which command to remove the user mary from a secondary group called team?

    the answer is wrong: # gpasswd -d user mary

    should be # gpasswd -d mary team
