The "VfsExampleShell" page has been changed by BerndEckenfels:
https://wiki.apache.org/commons/VfsExampleShell?action=diff&rev1=5&rev2=6

Comment:
Thanks to Dave Marion for HDFS example and testing.

  = Commons VFS Example Shell =
  This page shows some examples to configure the classpath and use the VFS Example Shell.
  
- All examples expect to be started from within the Apache Commons VFS source directory (refering
to build artifacts as well as external dependencies in a local maven repository). Linux/Unix
commands are marked with `$` prompt, for sample Windows command you see a `C:vfs>` prompt.
