Thanks PH, it helps.

How could I put a variable as part of a variable? I know I can do this: for i in a b c; do eval a$i=foo$i done echo $aa $ab $ac It will print out fooa foob fooc. But how could I get it using variable? I cannot use echo $a$i or p=\$a$i echo $p any idea? Thanks.

Thanks Vlad, I know how to solve this problem. I just don't know how the awk makes comparison. The first example shows, in awk 2>16d>10>2, how could this happen? The second example, why awk treats 16d and 60d differently? Thanks again. Shaoji
