RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
