your global variable is what ever is current in /tmp/myDumpfile.txt
just read it. it may change but if it's in a fixed location the information can either be read by others or given to others.
sample read from file;

#!/bin/sh


echo " READ FROM FILE - LOOP "
while read f
do
echo ""
echo " Doing something cool"
/usr/local/sbin/myshizz.sh
echo " TEST RESULTS for "$f

done < somedata.txt
