Guys,
I've updated my find duplicates script to work with the .xz packages. There are
actually 2 scripts involved:
'fduparch.sh' is the wrapper script that just sets the directories and options
for the actual duplicate finding script 'fduppkg'.
In its current configuration fduparch.sh actually calls fduppkg twice.
PASS 1:
it calls fduppkg to scan /var/cache/pacman/pkg and move any duplicates found to
'/home/backup/pkg-old'. Packages with the same name are then checked by DATE and
any older packages are moved /home/backup/pkg-old. This leaves only the current
packages in /var/cache/pacman/pkg making it much easing to move your install
from machine-to-machine without copying unneeded duplicates. Second, it frees up
space on / by moving duplicates to the /home partition.
PASS 2:
it calls fduppkg a second time to scan '/home/backup/pkg-old' and move any
duplicates found to '/home/backup/pkg-older'.
That way you have the latest packages in the normal '/var/cache/pacman/pkg' and
you have a duplicate-free set of the last packages before update in
'/home/backup/pkg-old'. All older versions are kept in '/home/backup/pkg-older'
The way I use the scripts is to create softlinks to the scripts in
/usr/local/bin (making sure /usr/local/bin is in your PATH) as follows:
ln -s /wherever/you/put/fduparch.sh /usr/local/bin/fduparch
ln -s /wherever/you/put/fduppkg /usr/local/bin/fduppkg
then I simply call fduparch after each update to clean the duplicates out of
/var/cache/pacman/pkg.
running fduppkg without arguments gives the general usage:
01:16 nirvana:/srv/http/dl/Archlinux/scripts> sh fduppkg
Usage: fduppkg <search dir> [ -d dup_dir -l logfile -s -v ]
Searches <search dir> for duplicate pkgs and moves duplicate files to [dup_dir]
or <search dir>/duplicates by default.
-d | --dupdir Used to specify directory to hold duplicate rpms
-l | --logfile Specify the log file name (default ./duplicates.log)
-s | --silent Don't output anything to stdout, just log results
-v | --verbose Output information showing which files are kept and not moved
However, to change the default duplicate directories, just edit the wrapper
script 'fduparch' and set the directories you want there. I have used a wrapper
script to keep fduppkg as flexible as possible so I can simply run it on any
package directory to find and move duplicates. (the split setup was originally
developed to handle suse's archane cache directory structure, but it handles
Arch's simple setup as well)
Grab the duplicate scripts at:
http://www.3111skyline.com/dl/Archlinux/scripts/fduparch.sh
http://www.3111skyline.com/dl/Archlinux/scripts/fduppkg
Finally, I have developed a script for determining which packages in
/var/cache/pacman/pkg are 'Installed' or not. The script is 'chkinstpkgs.sh' and
is available here:
http://www.3111skyline.com/dl/Archlinux/scripts/chkinstpkgs.sh
Running the script without argument will check the status of all packages in
/var/cache/pacman/pkg and provide you with a concise list of
installed/uninstalled packages in the following format:
01:24 alchemy:~/scr/arch> sh chkinstpkgs.sh
Determining installed/orphaned packages in /var/cache/pacman/pkg...
Initializing the package-information arrays
Checking installed packages
Total Number of Packages : 2713
Total Number Installed : 2225
Total Number Orphaned : 488
Updating the installed package array with installed/orphaned info
( be patient, time required is: [~30 sec/1000 pkgs] )
ORPHANS (pkg in /var/cache/pacman/pkg but not installed):
Total packages orphaned: 488
Package Arch Installed

<snip>
I find all 3 scripts useful in managing my Arch boxes and for moving installs
to new arch boxes. The chkinstpkgs.sh script is great for checking what I have
forgotten to install on a new box.
Enjoy!
