Could not open ... could not unlink ... /var/db/BootCache.playlist

Question

In 10.5.7, on my QS 2002 Dual 1GHz, I keep getting this message.
Awhile ago, someone suggested I Trash this file
/var/db/BootCache.playlist,
thinking it would be regenerated next Startup.
Is there a Terminal command that I can use to accomplish this? Something that would signle my OS X, to regenerate this file next go 'round?
Here are the log entries I find troubling:
Jul 20 17:43:33 localhost com.apple.launchctl.System[2]: BootCacheControl: could not open /var/db/BootCache.playlist: No such file or directory
Jul 20 17:43:33 localhost com.apple.launchctl.System[2]: BootCacheControl: could not unlink playlist /var/db/BootCache.playlist: Unknown error: -1
I see this in a number of other threads, but have not located a solution.
Thanks.

Even though I didn't get "data" on the second command, I went on and did all three
Moonstone-Art-Studio:~ moonstoneartstudio$ ls -l /var/db/BootCache.playlist
-rw------- 1 root wheel 58716 Jul 22 10:00 /var/db/BootCache.playlist
Moonstone-Art-Studio:~ moonstoneartstudio$ file /var/db/BootCache.playlist
/var/db/BootCache.playlist: cannot open /var/db/BootCache.playlist: Permission denied
Moonstone-Art-Studio:~ moonstoneartstudio$ BootCacheControl statistics
BootCacheControl: could not fetch cache statistics: Operation not permitted

Duh!
I forgot that I was root when I tried this. Try again:
sudo file /var/db/BootCache.playlist
sudo BootCacheControl statistics
(don't understand the [code] ... [code] posting/reply request):
You need to put before and after the Terminal output, and the second one does not need the '/' which most of these formatting systems (eg HTML) require. Note these are 'curly' brackets, not square ones.
