Returns the mount point of the given file, or itself if it cannot be found.

Example:

 Sys::Filesystem.mount_point('/home/some_user') # => /home

Returns the mount point for the given file. For MS Windows this means the root of the path.

Example:

   File.mount_point("C:\\Documents and Settings") # => "C:\\'

In block form, yields a Sys::Filesystem::Mount object for each mounted filesytem on the host. Otherwise it returns an array of Mount objects.

Example:

Sys::Filesystem.mounts{ |fs|

  p fs.name        # => '/dev/dsk/c0t0d0s0'
  p fs.mount_time  # => Thu Dec 11 15:07:23 -0700 2008
  p fs.mount_type  # => 'ufs'
  p fs.mount_point # => '/'
  p fs.options     # => local, noowner, nosuid

}

Yields a Filesystem::Mount object for each volume on your system in block form. Returns an array of Filesystem::Mount objects in non-block form.

Example:

   Sys::Filesystem.mounts{ |mount|
      p mt.name        # => \\Device\\HarddiskVolume1
      p mt.mount_point # => C:     #       p mt.mount_time  # => Thu Dec 18 20:12:08 -0700 2008
      p mt.mount_type  # => NTFS
      p mt.options     # => casepres,casesens,ro,unicode
      p mt.pass_number # => nil
      p mt.dump_freq   # => nil
   }

This method is a bit of a fudge for MS Windows in the name of interface compatibility because this method deals with volumes, not actual mount points. But, I believe it provides the sort of information many users want at a glance.

The possible values for the options and their meanings are as follows:

casepres => The filesystem preserves the case of file names when it places a name on disk. casesens => The filesystem supports case-sensitive file names. compression => The filesystem supports file-based compression. namedstreams => The filesystem supports named streams. pacls => The filesystem preserves and enforces access control lists. ro => The filesystem is read-only. encryption => The filesystem supports the Encrypted File System (EFS). objids => The filesystem supports object identifiers. rpoints => The filesystem supports reparse points. sparse => The filesystem supports sparse files. unicode => The filesystem supports Unicode in file names as they appear on disk. compressed => The filesystem is compressed.

Returns a Filesystem::Stat object that contains information about the path file system. On Windows this will default to using the root path for volume information.

Examples:

   Sys::Filesystem.stat("C:\\")
   Sys::Filesystem.stat("C:\\Documents and Settings\\some_user")

Returns a Sys::Filesystem::Stat object containing information about the path on the filesystem.
