This little program will do what you want.

<Start Script>
#!/bin/bash

# This script *MUST* be ran either
#   under sudo.

# The 'COLUMNS=200 dpkg -l' part
#   displays intalled packages

# The `awk '/^ii/ {print $2}' part
#   strips out the package names
#   from the previous list

# The 'xargs apt-get --reinstall install' part
#    uses each package name as an argument to
#    apt-get; 'the --reinstall install' tells
#    apt to reinstall the package if it is
#    already there

COLUMNS=200 dpkg -l | awk '/^ii/ {print $2}' | xargs apt-get --reinstall install
<End Script>
