Tukur,

Assuming that your file.txt is as follows:
val1 val2 val3

Here is a shell script:

#!/bin/sh
while read line
do
# store field 1
F1=$(echo $line|cut -d” ” -f1)
# store field 2
F2=$(echo $line|cut -d” ” -f2)
# store field
F3=$(echo $line|cut -d” ” -f3)
echo $F1 ” ” $F2 ” ” $F3
done < file.txt

Var $F1 $F2 and $F3 stores the value. If you need more help try out shell scripting forum @ http://forum.cyberciti.biz/
