rizky@rizky-laptop:~$ tar -xf test.tar rizky@rizky-laptop:~$ tar -xzf test.tar.gz rizky@rizky-laptop:~$
Clear view: clear
Actually this command doesn’t really clear your terminal’s view. It’s just make the terminal go down until the previous line unseen. If you scroll up your terminal you’ll see the previous line after some empty space.
rizky@rizky-laptop:~$ clear rizky@rizky-laptop:~$
Download and Install: apt-get

Done libapache2-mod-auth-mysql is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. rizky@rizky-laptop:~$
