What Others Think

But this is not correct. The command show you what could be installed (if the metadata is up-to-date). What you want is: dpkg -l ${PROGRAM} or apt-get policy ${PROGRAM}

apt-get policy is not correct either. Proper ways to do this include : dpkg -l bash | grep "^ii" apt-cache policy bash | grep Installed

ok, you are right, shows you the version you have installed, if you have installed, and shows you the version that should be installed if not already installed. Sorry, I know that my English is very bad.
