So first question is to use TAR to create a compressed archive of all files in the ETC
and the OPT directories and write this archive to your home directory. Notice that the question
does not ask for any name of the file. So let me use TAR, C, V, F, C for create, V for
verbose, and F for file. And oh, we need compression as well. Let me use J to create bzip2.compress
file. And I'm calling it slash root slash ETC and OPT.tar.bz2. It's nice to have an
extension here so that we can recognize what is in the file. And then we put in slash ETC
and slash OPT. That should be doing it. As always, I would advise to check the contents
of your archive. So TAR, T, V, F on ETC and OPT.tar. And there we can see the files that
are in the archive. So that looks successful. Second question, I create a symbolic link
to the archive you've just created in the TMP directory. So symbolic link, that means
ln-s of slash root slash ETC and OPT.tar.bz2 in slash TMP ETC and OPT.tar.bz2. So ls-l on TMP,
ETC, OPT, and TAR. And there we can see that it works. A symbolic link creates. Next, remove
the archive from your home directory. And what happens to the symbolic link? Well, let's use
rm-etcnopt and so on. And what happens to the symbolic link? Well, the symbolic link, as you
can see, is becoming invalid. So either you repair it or remove it, because right now
it doesn't work anymore.
