NAME
       fstyp - determine file system type

SYNOPSIS
       fstyp [-v] special

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  un-
       known_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.

OPTIONS
       -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  en-
       countering files	greater	than or	equal to 2 Gbyte ( 2**31 bytes).

ATTRIBUTES

NOTES
       The use of heuristics implies that the result of	 fstyp is not  guaran-
       teed to be accurate.
