 NAME
      fstyp - determine file system type

 SYNOPSIS
      /usr/sbin/fstyp [-v] special

 DESCRIPTION
      The fstyp command allows the user to determine the file system type of
      a mounted or unmounted file system.  special represents a device
      special file (for example: /dev/dsk/c1t6d0).

      The file system type is determined by reading the superblock of the
      supplied special file. If the superblock is read successfully, the
      command prints the file system type identifier on the standard output
      and exits with an exit status of 0.  If the type of the file system
      cannot be identified, the error message unknown_fstyp (no matches) is
      printed and the exit status is 1.	 Exit status 2 is not currently
      returned, but is reserved for the situation where the file system
      matches more than one file system type.  Any other error will cause
      exit status 3 to be returned.

      The file system type is determined by reading the superblock of the
      supplied special file.

    Options
	   -v	     Produce verbose output.  The output contains
		     information about the file system's superblock.

 RETURN VALUE
      fstyp returns the following values:

	   0	     Successful completion.
	   1	     Unknown file system type.
	   2	     File system matches more than one type.
	   3	     Usage error or access problem.

 EXAMPLES
      Find the type of the file system on a disk, /dev/dsk/c1t6d0:

	   fstyp /dev/dsk/c1t6d0

      Find the type of the file system on a logical volume, /dev/vg00/lvol6:

	   fstyp /dev/vg00/lvol6

      Find the file system type for a particular device file and also
      information about its super block:

	   fstyp -v /dev/dsk/c1t6d0
