How to find the most recent version of a package in the repositories?

How do I find the most recent version of a package in the repositories in a shell script? If I use apt-cache-policy, I get the installed version as "Candidate", not the most recent one from the repositories.

apt-cache policy nvidia-current shows:

nvidia-current:

  Installed: 280.13-0ppa~natty1

  Candidate: 280.13-0ppa~natty1

  Version table:

 *** 280.13-0ppa~natty1 0

        100 /var/lib/dpkg/status

     270.41.06-0ubuntu1 0

        500 http://archive.ubuntu.com/ubuntu/ natty/restricted amd64 Packages

It looks like the installed version is marked with ***, so that one must be ignored. Perhaps there is an awk script that could be used?

I suggest the following awk script, to which feed apt-cache policy output:

#!/usr/bin/awk -f



/^     [^ ]/ {

  version = $1

}

/^ *** [^ ]/ {

  version = $2

}

/^        [^ ]/ {

  server = $2

  if (server !~ /^//) {

    print version

    exit

  }

}
