st_ctime: time of most recent metadata change.

Unmounts a previously mounted block device from the given path.
Formats the specified path, must be either
/sd. A block device can also be passed like an SD object before being mounted.
Duplicate the terminal (the REPL) on the passed stream-like object. The given object must at least implement the
Separation character used in paths
