Top Forums Shell Programming and Scripting [KSH] Creating automatic variable from read input Post 302711693 by Don Cragun on Sunday 7th of October 2012 06:49:35 PM

I guess I'm really missing something here. Why do you believe that an array is needed here? Why not just keep a running total as you gather numbers? This is written assuming ksh, but should work for any POSIX-conforming shell (not csh and not tcsh):
Code:
#!/bin/ksh
GetNumMsg='Enter a number (ctrl-d when done): '
printf "$GetNumMsg"
sum=0
while read x
do      sum=$((sum + x))
        printf "$GetNumMsg"
done
printf "\nSum of numbers entered is: %d\n" $sum
