NCHECK_FFS(8) System Manager's Manual NCHECK_FFS(8)

ncheck_ffs, ncheck
generate names from inode-numbers

ncheck_ffs [
] [
-f format
] [
-i number ...
] filesystem

ncheck_ffs generates a list of filenames and inode numbers for the given file system. Names of directories are followed by a ‘.’. ncheck_ffs may be invoked more simply as ncheck, with no change in behaviour.
The options are as follows:
Print the file names ‘.’ and ‘..’, which are ordinarily skipped.
Use a custom output format when printing inode information. Characters from format are printed for each inode with the following escape sequences:
Print a ⟨bell⟩ character.
Print a ⟨backspace⟩ character.
Print an ⟨escape⟩ character.
Print a ⟨form-feed⟩ character.
Print the inode number.
Print a ⟨new-line⟩ character.
Print the pathname to the file using the current inode number.
Print a ⟨carriage return⟩ character.
Print a ⟨tab⟩ character.
Print a ⟨vertical tab⟩ character.
Print a ⟨single quote⟩ character.
Print a backslash character.
Print a NUL character.
All other characters, when prefixed by a backslash, simply print the character following the backslash. The device name is not printed on the first line of output when the -f option is specified.
number ...
Report only those files whose inode numbers are as listed.
Give more verbose information on inodes.
Report only special files and files with set-user-ID or set-group-ID set. This is meant to find hidden violations of security policies.
The report is not sorted.

The ncheck_ffs command was designed to be similar in functionality to the corresponding command in SunOS 4.1.3.
