What does the double asterisk(**) mean in the path?

There's two meaning of wildcards in paths for file collections.

* is a simple, non-recursive wildcard representing zero or more characters which you can use for paths and file names.
** is a recursive wildcard which can only be used with paths, not file names.

For examples,

/var/log/** will match all files in /var/log and all files in all child directories, recursively.
/var/log/**/*.log will match all files whose names end in .log in /var/log and all files in all child directories, recursively.
/home/*/.bashrc will match all .bashrc files in all user's home directories.
