yum-debug-restore
yum-debug-restore(1) yum-debug-restore(1) NAME
yum-debug-restore - replay Yum transactions captured in a debug-dump file SYNOPSIS
yum-debug-restore DESCRIPTION
yum-debug-restore is a program which takes a gzipped file created by yum-debug-dump and acts on the information about installed packages contained within. GENERAL OPTIONS
--output Output the commands that would be run to stdout. --shell=<file> Output the commands that would be run to a file. --install-latest Ask yum to install the latest version of the given packages, instead of the version that was installed in the debug-dump file. --ignore-arch Ignore the architecture of the packages, so you can "restore" an i386 debug-dump on an x86_64 machine. --filter-types=[install,remove,update,downgrade] Only perform the given types of commands, so you can filter to just upgrades and installs. FILES
As yum-debug-restore uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which repositories to use. Consult YUM documentation for details: /etc/yum.conf /etc/yum/repos.d/ /var/cache/yum/ SEE ALSO
yum-debug-dump (1) yum.conf (5) http://yum.baseurl.org/ AUTHORS
See the Authors file included with this program. BUGS
There are of course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. James Antill 15 December 2011 yum-debug-restore(1)
