Addition of numerical entries within a file

[Craig Basham]

For simplicity sake, imagine a file with a number of entries all on seperate lines. Each entry is a number. Is there a way of performing and addition function on all of these entries.

Eg.

File contents:

23
45
34
22
3

What command will tell me that the total of these numbers in this file is 127 ?

Indeed there is;

eg. your input file is called /tmp/tt

let X=0
for i in $(cat /tmp/tt)
do
let X=$X+$i
done
echo $X

This will display the total.

Hi,

here the awk solution:

awk '{sum+=$1}END{print sum}'

Regards

cat file | awk 'TOT==41 END {print TOT} '

[federico_3]

cat file | awk 'TOT+=$1 END {print TOT} '
