You could also write a shell script using lsof and grep out by the individual filename and append the grep output if found to another textfile. Although, I have to admit that it is not terribly effective.

Code:
#!/bin/sh

while true
  do
    sleep 1
    lsof | grep -i "MySpecialFile" >> paranoia.txt
done

Resulted in this output:

Code:
vi        3703    auswipe    3rW VREG 116,131078        159 1411444 /usr/home/auswipe/paranoid/MySpecialFile

The cheezy little script wasn't able to pickup that elvis had opened the file (copied to temp file for manipulation) and because the file was so small, lsof with a one second interval wasn't able to catch the file being copied.

There is bound to be a better solution for this type problem. I would suggest Google for searching.

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

NAME
home, 40meg, 80meg, personalize, update, Disclabel - administration for local file systems SYNOPSIS
gnot/home gnot/personalize gnot/update magnum/home magnum/personalize magnum/update pc/40meg pc/80meg pc/personalize pc/update nextstation/home nextstation/update DESCRIPTION
These programs help maintain a file system on a local disk for a private machine. Home partitions a disk, copies the appropriate kernel to the disk, and makes a new file system on the disk. To do this, it overwrites the vendor-supplied software on the disk with a copy of Plan 9. 40meg, 80meg, and 100meg configure disks and make file systems for disks of the appropriate size. Update copies the current kernel to the disk and updates files on the local file system. It only updates those files put there by the home program. Personalize removes the contents of the /usr directory on the local disk and copies a minimal set of files for the user who runs the com- mand. The file /rc/bin/nextstation/Disclabel, despite its name, is not an rc(1) script. It contains the second stage bootstrap program for Nextstations booting from local disk. Before booting a Plan 9 Nextstation from disk, it should be installed in the partition /dev/hd1label; this is normally done by nexstation/home. FILES
/lib/proto/portproto Mkfs prototype files for magnum/home, magnum/update, gnot/home, and gnot/update. /lib/proto/386proto Mkfs prototype files for pc/40meg, pc/80meg, and pc/update. SOURCE
