ncheck Command

Purpose

Generates path names from i-node numbers.

Syntax

ncheck [ [ [ -a ] [ -i InNumber ... ] ] | [ -s ] ] [ FileSystem ]

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.
