NAME
show-changed-rco - show changes in an RPM package SYNOPSIS
show-changed-rco [options] DESCRIPTION
show-changed-rco gives a compact description of the changes to a packages Requires, Conflicts and Obsoletes data from the installed (or old) to a specified rpm file. OPTIONS
-h, --help show this help message and exit -C, --cache Tells repoquery to run entirely from YUM cache - does not download any metadata or update the cache. Queries in this mode can fail or give partial/incorrect results if the cache isn't fully populated beforehand with eg "yum makecache". -c <config file>, --config=<config file> Use alternative config file (default is /etc/yum.conf). --repoid=<repo> Specify which repository to query. Using this option disables all repositories not explicitly enabled with --repoid option (can be used multiple times). By default repoquery uses whatever repositories are enabled in YUM configuration. --enablerepo=<repo> In addition to the default set, query the given additional repository, even if it is disabled in YUM configuration. Can be used multiple times. --disablerepo=<repo> Do not query the given repository, even if it is enabled in YUM configuration. Can be used multiple times. --repofrompath=<repoid>,<path/url> Specify a path or url to a repository (same path as in a baseurl) to add to the repositories for this query. This option can be used multiple times. If you want to view only the pkgs from this repository combine this with --repoid. The repoid for the repository is specified by <repoid>. --old-packages=<pkg> Explicitly list the valid old packages to match the new packages against. --ignore-arch Ignore arch. so you can compare foo-2.i686 to foo-1.x86_64. --skip-new Only give output for packages which we've found an old package for.
