Re^3: hard-to-understand taint error

It looks like your original requirement was files starting with '__'.

Similar to what ww is saying, you can simplify your capture to /^(__.*)$/; then you won't have to worry about upper-case matching.

But since we already grepped for `/^__/`, that can be simplified `/^(.*)$/`. Looks scary, but it's fine here. Either we trust `DB_DIREC` or we don't (in which case, it could be used to delete `/etc/__important` even with the "safer" untainting).	[reply] [d/l] [select]
