Thanks for the quick response DGPickett. I originally tried replacing the single quotes with double quotes for the sed portion of the script with no luck. I've gone ahead and replaced all single quotes with double quotes and still get the same exact output. Here is a copy of the updated scripted:
Code:
#!/bin/bash

while read SEARCH REPLACE
    do
        sed -e "s/$SEARCH/$REPLACE/" sourcefile
    done < <(awk "!/^#|^$/ { print $0}" controlfile)

And here is a copy of the output it yields:
Code:
search1


search2
search3
