pacundo
You know those times when you install some ArchLinux upgrades and it breaks your system, and now you have to go in and downgrade those packages? It's a pain ain't it? Well, this should make it slightly less of a pain (you may still have to boot from a USB depending on just how broken it is).
Installation
Dependencies
- Perl 5
File::ReadBackwardsmodule- PAR Packager (for compiling)
- GNU Makefile
You can install these packages with the following command:
# pacman -S perl perl-file-readbackwards perl-par-packer
Compiling & Installing
The script is compiled and installed using GNU Makefile. Therefore you can use
make install to build and install the script and its man-page as expected.
They are installed (by default) to /usr/local. To change this to a different
directory simply prepend the PREFIX=<path> to your make install command.
Usage
The first concept to understand is that of a transaction. A transaction is
defined in the pacman logs as package operations done during a single use of the
command (or so it seems, at least). If you look at the logs
(/var/log/pacman.log) this would be everything between the lines [ALPM] transaction started and [ALPM] transaction completed. You can set how many
transactions to list/undo by using the -t argument.
There are two modes for undoing pacman transactions:
- Interactive (
-i, default): will show you a numbered list with all the package operations of the selected transactions. - Automatic (
-r): will automatically undo all package operations of the selected transactions.
Look at the man-page (man pacundo) for more information.
