Hi all,

I'm trying to use a content of an array like array name but, doesn't work :(

this is my code:

Code:
groups[0]=group0
groups[1]=group1

group0[0]=value00
group0[1]=value01

group1[0]=value10
group1[1]=value11

for group in ${groups[@]};do
     sites=${!group}
     echo ${sites[@]}
done



Last echo print only the first value of arrays group0 and group1 not all value.

Any idea?

Thanks in advance and sorry for my not perfect English O:-)

Greetings
Gianluca

I fear variable indirection cannot be used for arrays. Eval will help you:
Code:
for group in ${groups[@]};do
    eval echo \$"{$group[@]}"
done
