test/directorylisting.sh run on a 500k line file takes too long

##  Test run

**test/directorylisting.sh**  Version 0.51

Did a test run on the **testfile**  using the above script.

the __testfile__ was a 500k+ line (70MB) file

Takes far long to process all the GREPs SEDs

A 100 line file take under 4 secs

There the estimated time to finish a 500k Row/Records is 5.5 hours

Is there a easier way?
