$ dpkg-query --showformat '${Version}\t${Status}\n' --show coreutils
8.23-4 install ok installed
$ dpkg-query --showformat '${Version}\t${Status}\n' --show coreutils | awk '/installed/ { print $1 }'
8.23-4
$ dpkg-query --showformat '${Version}\t${Status}\n' --show wowbagger
dpkg-query: no packages found matching wowbagger
$ echo $?
