Dynamic variable assignment

Hi All,

I have the below scenario:

A file test.cfg with three fields>>

DATA1 DATA2 DATA3

In the script I need to assign each of the fields to variables. The number of fields will not be constant (this case we have three). Im trying to do something like this:

NUM=1
OUT_DAT_NO=3

while [ $NUM -le $OUT_DAT_NO ]
do
OUT_DAT$NUM=`cat test.cfg | awk '{print $NUM}'`
NUM=`expr $NUM + 1`
done

The output should be like this:


OUT_DAT1=DATA1
OUT_DAT2=DATA2
OUT_DAT3=DATA3



Is there any way of doing this in bash?

Thanks,
D
