 NAME
      fsck - file system consistency check and interactive repair

 SYNOPSIS
      /usr/sbin/fsck [-F FSType] [-m] [-V] [special ...]

      /usr/sbin/fsck [-F FSType] [-o FSspecific-options] [-V] [special ...]

 DESCRIPTION
      The fsck command audits and interactively repairs inconsistent
      conditions for HP-UX file systems on mass storage device files
      identified by special.  If the file system is consistent, the number
      of files on that file system and the number of used and free blocks
      are reported.  If the file system is inconsistent, fsck provides a
      mechanism to fix these inconsistencies, depending on which form of the
      fsck command is used.

      special represents a special device (e.g., /dev/rdsk/c1d0s8).

    Options
      fsck recognizes the following options:

	   -F FStype	  Specify the file system type on which to operate
			  (see fstyp(1M) and fs_wrapper(5)).  If this option
			  is not included on the command line, then the file
			  system type is determined from the file /etc/fstab
			  by matching special with an entry in that file.
			  If there is no entry in /etc/fstab, then the file
			  system type is determined from the file
			  /etc/default/fs.

	   -m		  Perform a sanity check only.	fsck will return 0
			  if the file system is suitable for mounting.	If
			  the file system needs additional checking, the
			  return code is 32.  If the file system is mounted,
			  the return code is 33.  Error codes larger than 33
			  indicate that the file system is badly damaged.

	   -o FSspecific-options
			  Specify options specific to each file system type.
			  FSspecific-options is a list of suboptions and/or
			  keyword/attribute pairs intended for a file-
			  system-specific version of the command.  See the
			  file-system-specific manual entries for a
			  description of the specific_options supported, if
			  any.

	   -V		  Echo the completed command line, but perform no
			  other action.	 The command line is generated by
			  incorporating the user-specified options and other
			  information derived from /etc/fstab.	This option

			  allows the user to verify the command line.

 RETURN VALUES
      The following values are returned by the -m option to fsck:

	    0	Either no errors were detected or all errors were corrected.

	   32	The file system needs additional checking.

	   33	The file system is mounted.

      Return values greater that 33 indicate that file system is badly
      corrupted.  File system specific versions of fsck will have their own
      additional return values (see fsck_cachefs(1M), fsck_hfs(1M), or
      fsck_vxfs(1M)).

 WARNINGS
      This command may not be supported for all file system types.

 FILES
      /etc/default/fs	       Specifies the default file system type
      /etc/fstab	       Default list of file systems to check
