In fact, the entire, long pipe
Code:
cat $F | grep "^[a-z]" |awk '{print $1}' | sort | uniq -c| sort -rnk1

could be replaced by
Code:
awk '/^[a-z]/ {C[$1]++} END {for (c in C) print C[c], c}' $F | sort -nr

noted..good points thanks.. I thought it would not work in ksh , I had an impression that "expr" and "let" are the only way to do the math operation in ksh. Thanks for the improved codes .

Code:
i=(($i+1))

, it works
Thank You .. MadeInGermany

ksh introduced a lot of the more advanced syntax afaik... But many primitive versions of ksh continue to be distributed, which makes it a mixed bag.
