Hmmm, the blue sky and violet-pink clouds remind me of Arch homepage ;P
Hehe, it's a nice feeling, nevertheless.
@dkorzhevin: here's a script I've made when I needed this:
#!/bin/bash
echo -n "" > pkgNotFound
echo -n "" > pkgSums
names=`pacman -Slq`
for name in $names
do
versionLine=`pacman -Si $name | grep "Version : "`
version=`echo -n $versionLine | sed -e 's/Version : //g'`
md5Line=`pacman -Si $name | grep "MD5 Sum : "`
md5=`echo -n $md5Line | sed -e 's/MD5 Sum : //g'`
pkgPath=`find /var/cache/pacman/pkg/ -name $name"-"$version"*"`
if [ "$pkgPath" = "" ]
then
echo "Error: "$name" package not found in cache." >> pkgNotFound
else
echo $md5" "$pkgPath >> pkgSums
fi
done
exit 0
So your output will be located in the file "pkgSums" and it will look like this, these are the checksums that pacman displays, and the paths of your local packages:
4ce0d40359bfa1a4a0f47a0e53e65fa5 /var/cache/pacman/pkg/acl-2.2.49-1-x86_64.pkg.tar.xz
24df396b3146d1a203e0d4f4d6edd67b /var/cache/pacman/pkg/ar9170-fw-1.0-2-any.pkg.tar.gz
8454e0fc947f9c8ce4ac5c39ed6ef165 /var/cache/pacman/pkg/attr-2.4.44-1-x86_64.pkg.tar.gz
9ef6b0ce43a4660170df21ead2f8e711 /var/cache/pacman/pkg/autoconf-2.65-2-any.pkg.tar.xz
505fe675565601f6ca803779601837cf /var/cache/pacman/pkg/automake-1.11.1-1-any.pkg.tar.gz
To check the checksums against the packages, just run md5 with the newly created file, if you get output then something stinks :
# md5sum -c --quiet pkgSums
There's another file "pkgNotFound" for the packages which are found in pacman but not on your disk. So make sure you don't have these two files already, in the current directory, containing important information - they will be overwritten.
