NAME

ncheck_ffs, ncheck — generate names from inode-numbers

SYNOPSIS

DESCRIPTION

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:

-a

Print the file names ‘.’ and ‘..’, which are ordinarily skipped.

-f format

Use a custom output format when printing inode information. Characters from format are printed for each inode with the following escape sequences:

\a

Print a ⟨bell⟩ character.

\b

Print a ⟨backspace⟩ character.

\e

Print an ⟨escape⟩ character.

\f

Print a ⟨form-feed⟩ character.

\I

Print the inode number.

\n

Print a ⟨new-line⟩ character.

\P

Print the pathname to the file using the current inode number.

\r

Print a ⟨carriage return⟩ character.

\t

Print a ⟨tab⟩ character.

\v

Print a ⟨vertical tab⟩ character.

\'

Print a ⟨single quote⟩ character.

\\

Print a backslash character.

\0

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.

-i number ...

Report only those files whose inode numbers are as listed.

-m

Give more verbose information on inodes.

-s

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.
