I want to add a list of numbers in a file. Here's what I've tried.
Please help. Thanks:

#!/bin/ksh
#Script name:  myscript
sum=0
while read -u3 number_of_records
do
     print "$number_of_records"
     ((sum+=number_of_records))
done
print "$sum"
 3<$1

------------
$cat myfile
20
30
10
----------
$myscript myfile

You're redirecting the input to a null command that's executed after the 
loop is finished and the sum printed.  The redirection should be on the 
"done" line if you want it to be in effect during the while-loop.
