dcheck(8)
NAME
  dcheck - Checks directory consistency

SYNOPSIS
  /usr/sbin/dcheck [-i inumbers] [filesystem]

OPTIONS
  -i  The -i option is specified with a list of inumbers. If a specified
      inumber is found in a directory, the dcheck command displays the
      inumber, the inumber of the directory, and the name of the entry.

DESCRIPTION
  The fsck command supersedes the dcheck command for normal consistency
  checking.

  The dcheck command reads the directories in a file system and compares the
  link-count in each inode with the number of directory entries by which it
  is referenced. If a file system is not specified, a set of default file
  systems is checked.

  To get optimum performance, specify the raw version of the special file
  because the ilist is read in large chunks.

RESTRICTIONS
  Because the dcheck command uses two passes to check directories, it may
  produce erroneous diagnostics if active file systems are checked.

ERRORS
  If a file is found and the link-count and the number of directory entries
  do not agree, dcheck reports relevant information. Allocated files that
  have 0 link-count and no entries are also listed. A potentially dangerous
  situation occurs if there are more entries than links. If entries are
  removed and the link-count drops to zero (0), the remaining entries point
  to nothing should be removed. If there are more links than entries or if
  there is an allocated file with neither links nor entries, some disk space
  may be lost.
