Build array using Variable 1

[TSch]

Hi Folks,

I was wondering ... ;-)

I know I can create an Array using

set -A myarray $(cat filename.txt)

So ... Is it possible to do the same using Variables like that:

for i in sys1 sys2 sys3;
do
set -A AR$i $(cat /tmp/$i.txt)
done

Using the code from above I Keep getting the error message "This is not an identifier.". And another Problem would be that I have no idea how to reference elements within that Array later on ...

Like this:

echo ${AR$i[0]}

or

echo ${AR\$i[0]}

Regards,
Thomas

Have a look at the eval builtin.

Hope This Helps, PH.

Not sure if it helps, but is it just as easy to say:

for i in sys1 sys2 sys3;
do
set -A AR$i $(cat /tmp/$i.txt)
done

to something like:

for i in sys1 sys2 sys3;
do
AR$i=$(cat /tmp/$i.txt)
done
