Shell challenge

[ost]

This is a general shell question, but since Ive subscribed to this forum I may just ask here.. I hope you don't mind.
Im trying to grab a 2 line output by piping it to two read commands like this:
echo -e "1\n2"|(read l1;read l2)

Now, the l1 and l2 variable doesnt survive the end bracket (sub shell?). What's the easiest way to capture these and pass it to the main shell?

tests:
echo -e "1\n2"|(read l1;read l2;echo -e "$l1\n$l2");#works
echo -e "1\n2"|(read l1;read l2);echo -e "$l1\n$l2";#works not

I could add that this is supported in a shell that takes arrays:
line=(`echo -e "1\n2"`)

result:
line=([0]="1" [1]="2")

But microcore's shell doesnt seem to support that.

Not nice, but working:

Code: [Select]

eval $(echo -e "1\n2"|(read l1;read l2;echo "l1=\"$l1\" l2=\"$l2\""))To come up with a more sophisticated solution, I need a bigger context.

I find it nice and not nice at the same time Thanks
