fstyp


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  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.


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

OPTIONS
     -v           Produce verbose output. This is usually  infor-
                  mation  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  attri-
     butes:

NOTES
     The use of heuristics implies that the result of   fstyp  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 partition.
