I really don't know, but if you have to search for a high number of patterns it is better to use a pattern file instead of passing all the values on the command line!

Simply put all your patterns $D1 ... $D48 in a text file, one per line, and issue:

Code:
egrep -hi -f pattern_file.txt $file > $FILE4 2>> $FILE5
Have a look at the man page for more details.
