Command:   ncheck - i-node to name converter
Syntax:    ncheck [-i numbers] [-a] [-s] file_system
Flags:     -a  List all files, even . and ..
           -i  Followed by a list of i-nodes
           -s  List only special and setuid files
Examples:  ncheck - /dev/fd0        # List everything on /dev/fd0
           ncheck -i 10,15 /dev/fd0 # List i-nodes 10 and 15 on /dev/fd0

     Sometimes one knows about an i-node number and wants  to  find  the
file  name  that  goes  with  it.  This program makes that mapping.  The
default is to list everything on the device, but the -i  flag  restricts
the  list  to  specified i-nodes and the -s flag restricts it to special
files and setuid files (to look for possible security violations).
