How to hide invisible files on Leopard 10.5.7?

On Leopard 10.5.7, I had to unhide my invisible files for some job using the command:

#defaults write com.apple.finder AppleShowAllFiles YES
#killall Finder

I am trying the reverse commands but the Finder still shows files what are supposed to be hidden.

I tried:
defaults write com.apple.finder AppleShowAllFiles -bool false
defaults write com.apple.finder AppleShowAllFiles NO

followed by a killall Finder and even reboot.

I would like to avoid a re-install. Who can confirm a working solution as some in this forum suggest that the above reverse commands are no longer effective on Leopard?

Thx

 

Thanks, I tried the NO attribute but made no immediate difference. So I deleted the com.apple.finder.plist file and rebooted.

Now everything is OK.

Probably a combination of both ... but no need to reinstall )

 

Sorry, I should have said I tried with the attribute "OFF", I had tried "NO" and "-bool false"

Thx again
