Shell script “for” loop syntax

Question

I have gotten the following to work:

for i in {2..10}
do
    echo \"output: $i\"
done

It produces a bunch of lines of output: 2

Answer 1

Brace expansion, {x..y} is performed before other expansions, so you cannot use that for variable length sequences.

Instead, use the seq 2 $max method as user mob stated.

So, for your example it would be:

max=10
for i in `seq 2 $max`
do
    echo "$i"
done
