Korn shell in AIX (not sure about bourne shell or bash) have the ability
to do basic math.
-----------------
#!/usr/bin/ksh
TOTAL=0
NUMBERS=$(cat filename.txt)
for NUMBER in $NUMBERS; do {
TOTAL=$(($TOTAL + $NUMBER))
} done
echo $TOTAL
-----------------
$NUMBERS could also be
NUMBERS="1 2 3 4 10 55"
or
NUMBERS="1
2
3
4
10
55"
