On RHEL, version 5.4 and above,
I would like to extract and match the OCFS2 version with the Linux version:

#uname -r
  retruns:  2.6.18-371.3.1.el5PAE

# rpm -qa | grep ocfs
returns two rows:
  ocfs2-2.6.18-238.el5PAE-1.4.7-1.el5
  ocfs2-tools-1.4.4-1.el5

I need to find if the versions match:
 2.6.18-371.3.1.el5PAE with 2.6.18-238.el5PAE (This is from rpm cmd between the two "-")

Thanks

Try this:

rpm -q ocfs2 --qf '%{version}-%{release}\n'

The output should match the format of uname -r.

rpm -qa|grep ocfs2 |grep -v ocfs2-tools| cut -d "-" -f 2,3

Sorry, I didn't have ocfs2-tools installed anywhere to test with.  Nice work getting what you needed though!
