Bash: bad array subscript

Question

threads=`ls t[0-9][0-9]`       

for thread in \"${threads[@]}\"
do
       echo $thread
done

Expected result:

t01
t02
t10

Answer 1

Saying:

threads=`ls t[0-9][0-9]`

or

threads=\`ls t[0-9][0-9]\`

does not create an array.

In order to create an array, say:

threads=(ls t[0-9][0-9])

Moreover, avoid parsing ls.
