Ask a shell. . .

phoinix

The data in the a.ini file is as follows:

1
2
3
4
5
6
. . . .


There is a program that needs to get the data of each row in turn, and then fetch the data of the next row after the execution is completed. How to write this loop?

This program is very simple, read a newline to indicate the end of a line.

xman099

#!/bin/sh
content=`cat a.ini`
sum=0
for num in $content; do
#your operations
let sum=$sum+$num
echo $num
done

echo $sum

Thank you upstairs in advance

I am SOLARIS csh here, let’s not be used
let: not found

Also, the data of a.ini is irregular
901
345
567
. . . . . .

Use: bash let

wwll220

#!/bin/bash
cat a.ini | while read num
do
echo "$num"
#Design it yourself!
done
The above $num variable can get the value of each row in turn!
