Question

how to get directory content, and read file in it ?

But i can’t use commands and operators that included in this regexp:

/system|[)(\/}{`;,!\\*_]|open|exec|eval/

I think it’s a very hard task and i don’t known how to make it, please help me.

If this is homework, it’s one of the worse questions I’ve seen, so I’m assuming it’s not.

perl -E'say for glob chr 42'

or

perl -e'print qx^ ls ^'

or

perl -MFile::Find::Rule -MMIME::Base64 -E's^^decode_base64 "c2F5IGZvciBGaWxlOjpGaW5kOjpSdWxlLT5tYXhkZXB0aCgxKS0+aW4oJy4nKTs="^ee'

It’s really hard because we can’t use opendir or IO::Dir without using “;” or “,“, can’t use File::Find::Rule without using “(” and “)“, etc.
