 ncheck_hfs(1M)						      ncheck_hfs(1M)




 NAME
      ncheck - generate a list of path names from inode numbers for a HFS
      file system

 SYNOPSIS
      /usr/sbin/ncheck [-F hfs] [-V] [-S sector_ranges] [-i inode-numbers]
	   [-a] [-s] [special ...]

 DESCRIPTION
      ncheck, when invoked without arguments, generates a list of path names
      corresponding to the inode numbers of all files contained on the HFS
      file systems listed in /etc/fstab.  If special is specified, ncheck
      reports on the special only.  Path names generated by ncheck are
      relative to the given special.  Names of directory files are followed
      by /.

    Options
	   -a		  Allow printing of the names . and .., which are
			  ordinarily suppressed.

	   -F hfs	  Specify the HFS file system type.

	   -i inode-numbers
			  Report only on files whose inode numbers are
			  specified on the command line, in inode-numbers.
			  inode-numbers is a comma separated list of inode
			  numbers.

	   -s		  Report only on special files and regular files
			  with set-user-ID mode.  The -s option is intended
			  to discover concealed violations of security
			  policy.

	   -V		  Echo the completed command line, but performs 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.

	   -S sector_ranges
			  Report only on files using sector numbers
			  specified on the command line in sector_ranges.
			  sector_ranges is a comma separated list of sector
			  ranges.  A sector range is a starting sector
			  number and an ending sector number separated by a
			  dash, or just a sector number.  The sector numbers
			  should be in DEV_BSIZE units.	 If no pathname
			  contains the sector number it will be reported as
			  free or containing file system structure. Sectors
			  beyond the end of the file system will be reported
			  as illegal.

    Access Control Lists
      Continuation inodes (that is, inodes containing additional access
      control list information) are quietly skipped since they do not
      correspond to any path name.

 EXAMPLES
      Execute the ncheck command on all special in /etc/fstab:

	   ncheck

      Execute the ncheck command on HFS file system /dev/dsk/c1d2s0:

	   ncheck -F hfs /dev/dsk/c1d2s0

 EXTERNAL INFLUENCES
    International Code Set Support
      Single- and multi-byte character code sets are supported.

 DIAGNOSTICS
      When the file system structure is improper, ?? denotes the ``parent''
      of a parentless file and a path-name beginning with ... denotes a
      loop.

 AUTHOR
      ncheck was developed by AT&T and HP.

 FILES
      /etc/default/fs	       Specifies the default file system type.
      /etc/fstab	       Static information about the file systems.
