NAME

       fsck - file system consistency check and interactive repair

SYNOPSIS

       FSType] [special ...]

       FSType] FSspecific-options] [special ...]

DESCRIPTION

       The command audits and interactively repairs inconsistent conditions for HP-UX file systems on mass storage device files identified by spe-
       cial.  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, provides a mechanism to fix these inconsistencies, depending on which form of the command is used.

       special represents a special device (for example,

   Options
       recognizes the following options:

	      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 by matching special with an entry in that file.  If there is no entry in then the file  sys-
			     tem type is determined from the file

	      Perform a sanity check only.
			     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.

	      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.

	      Safe performance mode.  To improve performance, a system wide
			     will not be issued.  This feature is underlying file system dependent.

	      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 This
			     option allows the user to verify the command line.

RETURN VALUE

       The following values are returned by the option to

	      Either no errors were detected or all errors were corrected.

	      The file system needs additional checking.

	      The file system is mounted.

       Return values greater that indicate that file system is badly corrupted.  File system specific versions of 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.

       If  this  command  returns the message "Can't send after socket shutdown", check with your system administrator to make sure the is running
       properly.
