Greetings all;
Trying to sort out how to xz compress. But xz is rejecting directories,
like it expects tars output as its input. And the manpage is silent on
redirections.
I want to compress the directory foo into foo.xz, keeping foo as there
may be further patches applied in the future.
Syntax?
Thanks.
Cheers, Gene Heskett
