regex

I'm trying to read a file of regexes, looping over them and filtering them out of another file. I'm so close, but I'm having issues with my $regex var substitution I believe.

while read regex
do
  awk -vRS= '!/$regex/' ORS="\n\n" $tempOne > $tempTwo
  mv $tempTwo $tempOne
done < $filterFile

$tempOne and $tempTwo are temporary files. $filterFile is the file containing the regexes.
