            Bug ID: 27752
           Summary: -f behavior differs from GNU gzip
           Product: bzip2
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: bzip2
          Assignee: nobody at sourceware dot org
          Reporter: pgajdos at suse dot cz
                CC: bzip2-devel at sourceware dot org
  Target Milestone: ---

Manual page says:

-f

bzip2  normally declines to decompress files which don't have the correct m=
agic
header bytes.  If forced (-f), however, it will pass such files through
unmodified.  This is how GNU gzip behaves.

However:

$ echo hello world | bzip2 -dcf
$

in the opposite of:

$ echo hello world | gzip -dcf
hello world
$
