Cant' be fy.  That would cause it to look in the tar file called "y" for a
file called filename.tar.bz2.  The file name is always whatever comes
immediately after the f (ignoring whitespace), so you could do tar
-xzfhello.tar.gz and it would work, for example.

I think you mean tar -xvyf.  And I'm not sure if it's y or l.  Neither one
works even as late as RedHat 6.2 IOW, this is a _really_ recent addition
to tar, and you shouldn't count on it being there.  The only way to
extract bzip2 files with tar that's even _remotely_ general is to do
"bunzip2 -c filename | tar -xf -".  With gzip, by contrast, it has been
around long enough that you can usually get away with tar -xzf, as long as
you're not targeting Slowaris.  :-p

Later,
David
