NAME
ncheck_hfs: 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:
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.

Static information about the file systems.
