fstyp(1M)

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.

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.
