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

# NAME

`ncheck_ffs`, `ncheck` — generate names from inode-numbers

# SYNOPSIS

`ncheck_ffs` | [`-ams`] [`-f` format] [`-i` number ...] filesystem

# 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.

# HISTORY

An `ncheck` command appeared in Version 6 AT&T UNIX. The `ncheck_ffs` command was designed to be similar in functionality to the corresponding command in SunOS 4.1.3.
