Shell script to call apt-get install --reinstall

[Josh McKinney <forming@home.com>]

I am trying to call a shell script to reinstall all packages.  I have a file
that lists all installed packages called "file".  The problem is when I call the
script it just goes by saying it couldn't find the package.
Here is the script.

#!/bin/bash

cat file | (IFS=" " ; while read prog; do apt-get install --reinstall $prog; done)

Thanks
Josh
