sistem prog. odevi-ilk bölüm(Ad, Soyad, Numara ayırma)

subshell.sh

#!/bin/bash

while read line; do
        echo $line | awk -F, '{print $1}'
done < foo.txt > ad.txt
while read line; do
        echo $line | awk -F, '{print $2}'
done < foo.txt > soyad.txt
while read line; do
        echo $line | awk -F, '{print $3}'
done < foo.txt > numara.txt

DRY (don't repeat yourself)
while read line; do
echo $line | awk -F, '{print $1}' >> ad.txt
echo $line | awk -F, '{print $2}' >> soyad.txt
echo $line | awk -F, '{print $3}' >> numara.txt
done < foo.txt
