NAME         top

       repodiff - list differences between two or more Yum repositories

SYNOPSIS         top

       repodiff --old=old_repo_baseurl --new=new_repo_baseurl

DESCRIPTION         top

       repodiff is a program which will list differences between two
       sets of repositories.  Note that by default only source packages
       are compared.


       --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.

              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.

              Output a simple one line message for modified packages.

              Split the data for modified packages between upgraded and
              downgraded packages.

EXAMPLES         top

       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=
              --old=/tmp/repo-old --new=

       Compare x86_64 compat. binary pkgs, but also compare arch:
              repodiff -a x86_64 --compare-arch
              --old= --old=/tmp/repo-old
              --new= --new=/tmp/repo-new

       Compare two releases of Fedora (15 => 16):
              source-16&arch=i386' --size --simple --downgrade
