NAME

     fstyp_ufs -- check for a UFS volume

SYNOPSIS

     fstyp_ufs device

DESCRIPTION

     The fstyp_ufs utility is not intended to be run directly, but rather called by fstyp(8) while it is trying to determine which file system
     type is present on the given device.  It returns 1 if it thinks the device contains a UFS volume, and 0 otherwise.

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  sys-
       tem  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.

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 encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

NOTES

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