What's the difference between "tar -A" and "tar -r" ?


Any tar gurus lurking the newbie forums? I have a question for you:

--append and --concatenate look the same to me. What is the real difference between them?

the man page makes it pretty clear:

Quote:
-A, --catenate, --concatenate
append tar files to an archive

-r, --append
append files to the end of an archive
so -r will take a regular file list as input, -A will take an existing tar file.

I'm sorry, but the way it's formulated is not perfectly clear to me.
So, -A will take a tar archive and attach it to another tar archive?
And -r will take a regular file, compress it if specified, and add it to an existing archive?
Is this correct?
