`fusermount -u /tmp/tutorial/mnt`
* Changes to the file system are discarded. If you want to save the modified data to a new JSON file, add the `-o outputJsonFilePath` option when starting the program.

As its name indicates, it maps an existing file system subtree to a mount point of your choice. It demonstrates more advanced features such as file handles. The syntax is:
