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

This is a way:
Bash:

max=10
for i in $(bash -c "echo {2..${max}}"); do echo $i; done

The above Bash way will work for ksh and zsh too, when bash -c is replaced with ksh -c or zsh -c respectively.

Note: for i in {2..${max}}; do echo $i; done works in zsh and ksh.
