repodiff
repodiff(1) repodiff(1) NAME
repodiff - list differences between two or more Yum repositories SYNOPSIS
repodiff --old=old_repo_baseurl --new=new_repo_baseurl DESCRIPTION
repodiff is a program which will list differences between two sets of repositories. Note that by default only source packages are com- pared. GENERAL OPTIONS
--old, -o Add a repo. as an old repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and not a baseurl. --new, -n Add a repo. as an new repo. Note that if you prefix the url with "mirror:" then the following url is treated as a mirror and not a baseurl. --archlist, -a Add architectures to change the default from just comparing source packages. Note that if you want the same as a native "x86_64" architecture machine you just need to pass "x86_64" (this is different from earlier versions where you needed to specify "x86_64,athlon,i686,i586,i486,i386,noarch" and you still got "src"). --size, -s Output additional data about the size of the changes. --compare-arch Normally packages are just compared based on their name, this flag makes the comparison also use the arch. So foo.i386 and foo.x86_64 are different. --simple Output a simple one line message for modified packages. --downgrade Split the data for modified packages between upgraded and downgraded packages. EXAMPLES
Compare source pkgs in two local repos: repodiff --old=/tmp/repo-old --new=/tmp/repo-new Compare x86_64 compat. binary pkgs in two remote repos, and two local one: repodiff -a x86_64 --old=http://example.com/repo1-old --old=/tmp/repo-old --new=http://example.com/repo1-new --new=/tmp/repo-new Compare x86_64 compat. binary pkgs, but also compare arch: repodiff -a x86_64 --compare-arch --old=http://example.com/repo1-old --old=/tmp/repo-old --new=http://example.com/repo1-new --new=/tmp/repo-new Compare two releases of Fedora (15 => 16): repodiff --old='mirror:https://mirrors.fedoraproject.org/metalink?repo=fedora-source-15&arch=i386' --new='mirror:https://mir- rors.fedoraproject.org/metalink?repo=fedora-source-16&arch=i386' --size --simple --downgrade SEE ALSO
