Sum up numbers in a file? 1

[jouell]

Can someone point me in the right direction (the search is not working now).

If I have a file w/10 number in it, how can I sum them up in ksh? Is there a better unix util to do it other than ksh?

thanks!

#!/bin/ksh

i=0
while read line
do
        ((i+=line))
done < x
print $i

where x is the file that contains the numbers:
1
2
3
4
5
6
7
8
9
10

what's your sample file?

vlad
+----------------------------+
| #include<disclaimer.h> |
+----------------------------+

If you are not using whole numbers, I would suggest using ksh93.

#!/usr/dt/bin/dtksh

float i=0
while read line
do
        float a=$line
        ((i+=a))
done < x
print $i

If your numbers file contained:
1.23
2.374
3.833
4.435
5.34477
6.0432573
7
8.2
9
10.26262624

or:

(tr '\n' '+' < file ; echo '0') | bc

vlad
+----------------------------+
| #include<disclaimer.h> |
+----------------------------+

Another way:
tot=$(awk '{t+=$1}END{print t}' /path/to/file)

Hope This Helps, PH.
