Description Karel Srot 2012-03-09 08:56:09 UTC
Description of problem:

on RHEL6 file -z cannot extract bzip2 archives when using -z option

file-5.04-6.el6.x86_64
$ file -z gfs1partition.bz2 
gfs1partition.bz2: data (bzip2 compressed data, block size = 900k)

this is working on RHEL5:

file-4.17-20
:: [   PASS   ] :: Running 'file -z gfs1partition.bz2 &> log1'
gfs1partition.bz2: Linux GFS1 Filesystem (blocksize 4096, lockproto lock_nolock) (bzip2 compressed data, block size = 900k)

Comment 1 Karel Srot 2012-03-09 10:35:18 UTC
also tested with file-5.04-11.el6 and file-5.04-13.el6, still not working.

Comment 2 Jan Kaluža 2012-03-09 11:32:20 UTC
It's bug file-5.x branch caused by addition of built-in zlib decompressing support.
