  NAME
       fstyp - determine file system type
  
  SYNOPSIS
|      fstyp [-a | -v] special[:logical-drive]
  
  
       fstyp allows the user to determine the file system  type  of
       unmounted file systems using heuristic programs.
  
       An  fstyp module for each file system type to be checked  is
       executed;   each  of  these  modules  applies an appropriate
       heuristic to determine whether the supplied  special file is
       of  the  type  for  which  it  checks. If it is, the program
       prints on standard output the usual file  system  identifier
       for that type (for example, ``ufs'') and exits with a return
       code of  0; if none of the modules succeed, the  error  mes-
       sage   unknown_fstyp  (no  matches) is returned and the exit
       status is  1. If more than one module  succeeds,  the  error
       message unknown_fstyp (multiple matches) is returned and the
|      exit status is 2. Other errors are printed in the same format.
  
|      -a       Output all available filesystem attributes.
|               If a file system was successfully identified, and
|               this option is specified, then the FSType identifier
|               is followed by one or more name-value pairs,
|               one per line, in the format:
|               
|                   name: value
  
|               String values are put in single quotes.
| 
|               Nested name-value list increases indentation of its
|               values by 4 whitespaces.
|               
|               For an array of name-value pairs, one array entry
|               is printed per line, with the index following the
|               name in square brackets.
|               
|               Example:
|               
|                   top_string: 'String'
|                   top_list:
|                       string_array[0]: 'S0'
|                       string_array[1]: 'S1'
|                       list_array[0]:
|                           int_one: 1
|                           string_two: 'S2'
|                       list_array[1]:
|                           int_array[0]: 1
|                           int_array[1]: 2
|                           int_array[2]: 3
| 
|               In the above example, 'top_list' is a name-value list,
|               consisting of a string array 'string_array' and a
|               name-value list array 'list_array'. The second
|               'list_array' element is an integer array 'int_array'
|               containing three elements.
| 
|               In addition to FSType-specific attributes, following
|               generic attributes may be present:
|               
|               gen_clean
| 
|                   Allowed values are  "true" and "false".  If  the
|                   value is "false", the file system is damaged  or
|                   was not unmounted cleanly and fsck(1M) is required
|                   before this file system can be mounted.
| 
|               gen_guid
|               
|                   Globally unique identifier. A string that
|                   uniquely identifies the file system.
| 
|               gen_version
|               
|                   A string describing the file system version.
| 
|               gen_volume_label
|               
|                   Volume label, a human-readable string used to
|                   describe and/or identify the file system.
| 
| 
       -v       Produce verbose output. This is usually information
                about the file systems superblock and varies across
                different FSTypes.  See    ufs(7FS),  mkfs_ufs(1M),
                and  tunefs(1M) for details.
  
  USAGE
       See largefile(5) for the  description  of  the  behavior  of
       fstyp  when  encountering  files  greater than or equal to 2
       Gbyte ( 2**31 bytes).
  
       See attributes(5) for descriptions of the  following  attri-
       butes:
       ____________________________________________________________
      |       ATTRIBUTE TYPE        |       ATTRIBUTE VALUE       |

       The use of heuristics implies that the result of   fstyp  is
       not guaranteed to be accurate.
