Commands Reference, Volume 4
ncheck Command
Purpose
Generates path names from i-node numbers.
Syntax
ncheck [ [ [ -a ] [ -i InNumber ... ] ] | [ -s ] ] [ FileSystem ]
Description
The ncheck command displays the
i-node number and path names for filesystem files. It uses question marks
(??) displayed in the path to indicate a component that could not be found.
Path names displayed with ... (ellipses) at the beginning indicate either
a loop or a path name of greater than 10 entries. The ncheck command uses a simple hashing alogrithm to reconstruct the path names
that it displays. Because of this, it is restricted to filesystems with less
than 50,000 directory entries.
Flags
-a |
Lists the . (dot) and .. (dot dot) file names. |
-i InNumber |
Lists only the file or files specified by the InNumber parameter. |
-s |
Lists only special files and files with set-user-ID mode. |
Examples
- To list the i-node number and path name of each
file in the default file systems, enter:
ncheck
- To list all the files in a specified file system,
enter:
ncheck -a /
This lists the i-node number and path name of each
file in the / (root) file system, including the .(dot)
and .. (dot dot) entries in each directory.
- To list the name of a file when you know its i-node
number, enter:
ncheck -i 690 357 280 /tmp
This
lists the i-node number and path name for every file in the /tmp file system with i-node numbers of 690, 357, or 280. If a file
has more than one link, all of its path names are listed.
- To list special and set-user-ID files, enter:
ncheck -s /
This lists the i-node and path name for every file
in the / (root) file system that is a special file (also
called a device file) or that has set-user-ID mode enabled.
