NAME
       fstyp - determine file system type

SYNOPSIS
       fstyp [-a | -v] special [:logical-drive]

DESCRIPTION
       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  message
       unknown_fstyp (no matches) is returned and the exit  status  is	1.  If
       more  than one module succeeds, the error message unknown_fstyp (multi‐
       ple matches) is returned and the exit status is	2.  Other  errors  are
       printed in the same format.

       This  command  is unreliable and its results should not be used to make
       any decisions about subsequent use of a storage device or  disk	parti‐
       tion.

OPTIONS
       -a    Output all available file system attributes. If a file system has
	     been successfully identified, and this option is  specified,  the
	     FSType  identifier is followed by one or more "name-value" pairs,
	     one per line, in the format:

	       name: value

	     The following conventions are  recognized	for  the  file	system
	     attributes:

		 o	String values are put in single quotes.

		 o	Nested	"name-value" list increases the indentation of
			its values by four whitespaces.

		 o	For an array of "name-value" pairs, one array entry is
			printed per line, with the index following the name in
			square brackets.
	     For instance, in the following 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"ele‐
	     ment is an integer array "int_array" containing three elements.

	       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	 addition  to  the  FSType-specific  attributes, the following
	     generic attributes may be present:

	     gen_clean	  Allowable values are "true" or "false". If the value
			  is  "false",	the  file system is damaged or was not
			  unmounted cleanly and the fsck(1M) command  must  be
			  run before this file system can be mounted.

	     gen_guid	 Globally  unique  identifier.	This  string  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
				 either describe 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).

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

       ┌─────────────────────────────┬─────────────────────────────┐
       │      ATTRIBUTE TYPE	     │	    ATTRIBUTE VALUE	   │
       ├─────────────────────────────┼─────────────────────────────┤
       │Availability		     │SUNWcs			   │
       └─────────────────────────────┴─────────────────────────────┘

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

       This command is unreliable and its results should not be used  to  make
       any  decisions  about subsequent use of a storage device or disk parti‐
       tion.
