How can I trigger brace expansion inside a script?

Question

I'm writing a script which needs to use the shell's brace expansion, but nothing I've tried works. For (a contrived) instance, say I have a variable containing the string

thing{01..02}

and I (obviously) want to expand it to

thing01 thing02

from inside the script, how can I do that?

(For anyone who assumes this is a duplicate of this other question, please read them more carefully. That question is regarding working from the shell, not a shell script, and doesn't require the ability to expand arbitrary expressions.)

What have you so far in your script? – Reto Aebersold Aug 16 '11 at 16:15 — Reto Aebersold, Aug 16 '11 at 16:15

Make sure that braceexpand is turned on with set -o braceexpand.

When I wrote it in bash script, I got `set: 2: Illegal option -o braceexpand` – user13107 Apr 05 '13 at 05:02

It seems problem was because I was running it as `sh script` instead of `bash script`. Also added that line in bashrc instead of script. – user13107 Apr 05 '13 at 05:07
