I created an Ubuntu minimal installation on a VirtualBox VM. Then, I decided to archive it so that I could share it with friends. I am letting them use it so that they can experiment with Linux commands.
I archived it using the command,
tar -zcvf ./Hackcraft.tar.gz ./Hackcraft
The archive process worked great. However, when I opened the archive in FileRoller, I noticed that the first visible directory is "." without quotes. When I double-clicked on that directory to look inside it, I saw my Hackcraft folder, which was archived. In it was all of my files.
The question is, why is the top-level folder .? I know that it is used, for example, when cd'ing in a terminal, to denote the current folder. But why is it there?
