I'm interested in unpacking an rpm so I can get at the files without having to go through the install process. There don't seem to be any options for this using either the
rpm commands. My goal is to then modify and then rebuild the rpm. Is there a way to do this?
you could unpack rpm using command
rpm2cpio package.rpm | cpio -i --make-directories
If you want to modify package, the better way is to download package.src.rpm file, install it using
rpm -i package.src.rpm. This would place sources to /usr/src/redhat/SOURCES. You could patch sources and modify spec file located in /usr/src/redhat/SPECS/ and then rebuild package using
rpmbuild -bb /usr/src/redhat/SPECS/package.spec
