       apt-show-versions - Lists available package versions with distribution

       apt-show-versions parses the dpkg status file and the APT lists for the
       installed and available package versions and distribution and shows
       upgrade options within the specific distribution of the selected

       This is really useful if you have a mixed stable/testing environment
       and want to list all packages which are from testing and can be
       upgraded in testing.

       apt-show-versions uses caching for the status information of installed
       and available packages. If you run apt-show-versions as root the cache
       is updated as needed. If you run as non-root uses the newest available
       information, but can't update the cache. If you run as root with the
       option -i the cache is initialized or updated only.

       apt-show-versions [-h] [[-p] package name] [-a] [-b]

       If you don't give any options the status of all installed packages is

       -p package, --package=package
           Print available and installed versions for specified package. You
           can also specify a package name without the option -p. If -p and a
           package name are missing, all installed packages are displayed.

       -r, --regex
           interpret package from option -p as a regex.

       -R, --regex-all
           like --regex, but also show matching packages which are not

       -u, --upgradeable
           Print only upgradeable packages

       -a, --allversions
           Print all available versions of the selected packages

       -b, --brief
           Print only package_name/distribution for upgradeable packages

       -v, --verbose
           Prints out verbose messages.

       -i, --initialize
           Initialize or update package cache only (as root). Do this every
           time when the status of the installed or available packages has

       -stf file, --status-file=file
           Use file as the dpkg status file instead of /var/lib/dpkg/status

       -ld directory, --list-dir=directory
           Use directory as path to apt's list files instead of
           /var/state/apt/lists/ or /var/lib/apt/lists/

       -h, --help
           Prints out command-line help.

       0   No error

       1   Wrong usage

       2   apt-show-versions has been called with exactly one package and
           upgradeable option set, but package is uptodate. As no output has
           been requested, this case gets signaled using the exit code.

       255 Unspecified error

       If you want to know for all your installed packages whether they are
       uptodate or upgradeable, use:


       If you want to have a list of all upgradeable packages:

           apt-show-versions -u

       To get a list of all available versions of libc6:

           apt-show-versions -a -p libc6

       To get information about several packages:

           apt-show-versions dpkg apt

           apt-show-versions -r ^texlive

       To upgrade all packages in testing:

           apt-get install `apt-show-versions -u -b | fgrep testing`
