This is the column of Inputs

2434
7870
843

How could I sum them by unix command?
Do I have to use loop?

Hi:

Three other ways:

#!/bin/ksh
# integer arthmetic

# ksh
x=$((2434 + 7870 + 843 + 9087))
echo $x

# sh
x=`expr 2434 + 7870 + 843 + 9087`
echo $x

# bc
x=$(bc << EDS
scale=1
2434 + 7870 + 843 + 9087
EDS)
echo $x

Regards,

Ed
