Although this is not cause of the "Bad File Descriptor" message, a small observation about your sample code: it is a good idea to get in the practice of assigning things like $! (os error), $? (child error) and $@ (thrown exception) $^E (extended OS error) and so on to a variable immediately after the call that generates them. If you are not watchful, the code to process them can accidentally reset them.

The practice of assigning them straight away to a named variable prevents this and many a wild goose chase looking for bugs.

Best, beth
