This is a "user" problem. You are using the wrong features for the task, your code should read:
| for f in *; do ./test "$f"; done and quote all other variable expansions. NEVER do: for foo in `...` OR for foo in $(...( This is wrong, because you're relying on word splitting and glob expansion, which is wrong 99% of the cases.
