hxmuller/verify integrity of all installed Debian packages

## verify integrity of all installed Debian packages
# dpkg - package manager for Debian
#   -V  Verifies the integrity of package-name or all packages if omitted
#
#   The output format:
#
#   SM5DLUGT c <file>
#
#   Where:
#   S is the file size.
#   M is the file's mode.
#   5 is the MD5 checksum of the file.
#   D is the file's major and minor numbers.
#   L is the file's symbolic link contents.
#   U is owner of the file.
#   G is the file's group.
#   T is the modification time of the file.
#   c appears only if the file is a configuration file. This is handy for
#     quickly identifying config files, as they are very likely to change,
#     and therefore, very unlikely to verify successfully.
#   <file> is the file that failed verification. The complete path is listed
#     to make it easy to find.
