On the other hand, there is no apt way to tell apt-cache to print all
installed packages and their versions. What about an `list' command for
apt-cache? Its output could be (some kind of combination of both
existing apt-listrepository implementations):
name1 version1 uri1 distribution1/component1
name2 version2 uri2 distribution2/component2
...
This would be a superset of apt-listrepository and also a substitute for
dpkg -l in many cases. If someone requests this, an output modifier to
additionally show pinning could be added to a later apt release.
So, my wishlist currently is `apt-cache list' and `apt-cache unavail' :)
The latter would be equivalent to:
apt-cache list | grep /var/lib/dpkg/status
