Hello,

I would like to process a sum on a file :
for exemple :

4
5
3

Sum is 12

I tried with the "+" but it doesn't seems to work on the sun or maybe I use a wrong syntax, my script is as follow:
---------------------------
export Value
export TotalValue

while read Valeur
do
TotalValue= eval $TotalValue + $Value
done < $1

echo $TotalValue
--------------------------------

Thank you for your help!

awk '{c += $0} END{print c}' input_file

Cheers
ZB

Thank you ,

in fact this scripts works :

-------------------------------------
export Valeur=0
export ValeurTotale=0

while read Valeur
do
ValeurTotale=`expr $ValeurTotale + $Valeur`
done < $1

echo $ValeurTotale
----------------------------------------

I have got another problem, it works for numerics without decimals but I need to sum decimals, it seems I need to declare my variables as decimals ? do you know how to do that ?
Does anyone got an idea ????

thank you for your help it's very urgent

Zazzybob !! pleaaaaaaase

I used the awk to sum my file.

it works for "little" sums, but for one file I should have :

25 109 979 252.36

and I have the following result :

9,18618e+08


How should I interpret this result ? is there a limit with the awk calculation?

Thank you for your help

Cécile

My solution:

Code:

#! /usr/bin/ksh

bc |&
ValeurTotale=0.00

while read Valeur ; do
        print -p $ValeurTotale + $Valeur
        read -p ValeurTotale
done < $1

echo $ValeurTotale
exit 0
