       fsck - file system consistency check and interactive repair

       FSType] [special ...]

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

       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,

	      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 match‐
			     ing special with an entry in that file.  If there
			     is no entry in  then  the	file  system  type  is

			     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 sys‐

	      Specify options specific to each file system type.
