Abstract
Documentation:
This is the epoch number of the RPM, this is used as a kludge for version-release comparisons where the vendor has done some kind of re-numbering or version forking. This number is not revealed by a normal query of the RPM's information -- you must use a formatted rpm query command to gather this data from the command line, like so. For an already-installed RPM: rpm -q --qf '%{EPOCH}\n' installed_rpm For an RPM file that has not been installed: rpm -qp --qf '%{EPOCH}\n' rpm_file
