What does ** mean in Phing?

Question

The Phing User Guide uses the following file filter description **:

"Two asterisks (**) may contain above the" border "of the directory separator."

I find it difficult to determine what this really means. Can someone please translate this into English?

Answer 1

** matches any character, and * matches anything other than a directory separator.

For example, /path/** will match one of the following:

• / path / file
• / path / to / some / file
• / path / to / some / others / file

However, /path/* will match only one.
