Package: xz-utils
Version: 4.999.8beta-1
Severity: normal
Xz does not implement a very useful feature found in gzip and bzip2 when
using the --force option. This is the relevant bzip2 doc:
bzip2 normally declines to decompress files which don't have the
correct magic header bytes. If forced (-f), however, it will
pass such files through unmodified. This is how GNU gzip
behaves.
As an example of how this could be useful, here is a pipeline that
decompresses stdin be it compressed with gzip or bzip2, and leaves it
untopuched if it is not compressed:
bzip2 -cdfq | gzip -cdfq
However, extending it to also decompress xz fails:
bzip2 -cdfq | xz -cdfq | gzip -cdfq
because xz does not let an unrecognised file pass through.
