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
and I (obviously) want to expand it to
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.)
