CentOS - Jan 2013 - How to extract one file from rpm using yum?

I want to get the original version of /etc/clamd.d/amavis.conf from the 
amavisd-new rpm to get the defaults to submit a bug report.  I could not 
figure out how to do this, so I did a reinstall, but it did not replace 
this file (whatprovides says it comes from this rpm).

Is there a way to extract just the one file, and better yet, place it 
elsewhere than its regular destination?

thanks

Hi Robert,

you can extract this file with cpio or open it with mc like a archive 
(zip, tar, ...)

Didn't it create it in the normal destination as amavis.conf.rpmnew?

You could also just have renamed your conf file temporarily, 
reinstalled, moved the default conf file and renamed back 
your conf file...

OK.  I am set for what I needed.  I went to the repo via http and 
downloaded the rpm.  I then used archive manager via nautilus to get to 
the file(s) I needed.  Now to write up the bug report.  Minor item, but 
it bugs me.... ;)

The command line way of getting 1 file out of a rpm is to rpm2cpio.

    rpm2cpio <rpmfilename> > <filename.cpio>

Now you have a cpio archive which you can use to get files out of.

Actually very old to it.  I use to do this stuff 10 years ago and my 
brain just ain't what it use to be.  Use to do my own builds for a 
number of apps, but doubt I could do a build now!

And one more:

To extract a single file from a package

 rpm2cpio gnupg-1.2.6-6.src.rpm | cpio -ivd gnupg.spec
