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 compared.
GENERAL OPTIONS
--old, -o
Add a repo. as an old repo.
--new, -n
Add a repo. as an new repo.
--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.
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
