Description Shaun Bouckaert 2010-05-21 20:35:53 UTC 
When trying to extract an xz archive, I was unable to use the --xz or -J options listed in the man page.

Reproducible: Always

Steps to Reproduce:
1. tar -xv --xz -f /usr/portage/distfiles/libpng-1.2.43.tar.xz
2. tar -xvJf /usr/portage/distfiles/libpng-1.2.43.tar.xz
Actual Results:  
tar: unrecognized option `--xz'
Try `tar --help' or `tar --usage' for more information.

tar: invalid option -- J
Try `tar --help' or `tar --usage' for more information.

tar 1.20 doesn't support those options, nor does it list them in the man page.

They are certainly listed on my system. I had downgraded back to this version to check though, so perhaps the man page wasn't downgraded also...

You're probably looking at the cached man page.  use man -c to reformat the man page.
Comment 4 SpanKY gentoo-dev 2010-05-24 20:40:46 UTC 
there is only one man page maintained for all versions.  if, for some weird reason, you re-installed tar-1.20, you'd probably get a newer man page.  i dont think it's worth changing this since a newer tar is going to go stable soon.
