"rpm -q --whatprovides /sbin/ifconfig" is the same as "dpkg-query
--search ifconfig".
Looking at the archive, the OP's problem seems to be that he's
querying many/all packages and virtual packages return "$unknown". On
an Ubuntu 12.04 box:
[root:~]# apt-cache show awk
N: Can't select versions from package 'awk' as it is purely virtual
N: No packages found
[root:~]# dpkg-query --showformat '\${status}\t\${version}\n' -W awk
$unknown ok not-installed $
[root:~]# dpkg-query --showformat '\${status}\t\${version}\n' -W gawk
$install ok installed $1:3.1.8+dfsg-0.1ubuntu1
[root:~]# dpkg-query --showformat '\${status}\t\${version}\n' -W mawk
$install ok installed $1.3.3-17
[root:~]#
The OP could filter out virtual packages with "dpkg
--get-selections"/"aptitude search '?virtual'"/"aptitude search
'?installed'".
[root:~]# dpkg --get-selections | grep awk
gawk install
mawk install
[root:~]# aptitude search '?virtual' | grep awk
v awk -
v awk:i386 -
[root:~]# aptitude search '?installed' | grep awk
i A gawk - GNU awk, a pattern scanning and processing
i mawk - a pattern scanning and text processing lan
[root:~]#
