Is it possible to unpack rpm change file then repack?
 

I have a binary rpm without the source rpm and I would like to change a file that gets installed (without having to do it post-install).

Is there a tool that can extract the files from an rpm so that I can make the change, and then be able to pack it back into a working rpm again?

Also it would be good if it was possible to change the version number during this process as well.

Thanks.

rpm2tgz
rpmbuild

Thanks, but that only seems to extract the files without creating any spec listing the information and dependencies of the rpm.

So when I tried to build it with rpmbuild it complained that the name, version, release etc must be present in package.

Do I have the wrong version of rpm2tgz or is there some other way of extracting the spec with the files?

Thanks.
