[Dizziness] I did a dizziness today 18, tar -xzvf /tmp/b/b.tar.gz /tmp/b/*

Looking at other people's code today and seeing the execution of this command, I thought there was a problem at first; because the files used were all files under /tmp/b/; later, I didn't see the problem
when I actually executed it. , first look at all the files under /tmp/b/, and then create new files;
so there is no big problem in execution.

But it always feels weird, you have to get used to it.
Or don't write this misleading command.
