I'm using Mac OS 10.6.7 on a low memory MacBook, so I would like to kill the Dashboard and not have it running at login. Tried this

    defaults write mcx-disabled -boolean YES 

...but couldn't make it work.

That last sentence provides absolutely no information, since you fail to mention which commands didn't work for you. – Daniel Beck Jul 24 '11 at 19:01
Thanks for the comment Daniel, I've added the command now. – villares Jul 24 '11 at 19:14
Have you logged out and back in since entering the command? – Daniel Beck Jul 24 '11 at 19:18
@DanielBeck Or reopened Dock. – user495470 Jul 24 '11 at 19:21
Yes, I've logged out and back. Didn't work :( – villares Jul 24 '11 at 19:27

Enter the following Terminal command:

defaults write mcx-disabled -bool true && killall Dock

It worked for me.

Thanks for the reply, something else is going on. It didn't work for me. – villares Sep 16 '11 at 12:12
@villares To clarify, Dashboard is still running although you set this command? – Daniel Beck Sep 16 '11 at 12:41
Still works with 10.8. – Max Howell Jul 30 '12 at 22:44
I typed sudo in front of it, just in case. – bobobobo Sep 7 '12 at 16:38
@bobobobo defaults manages user defaults, or, in other words, preferences. Some of them are hidden, but they're almost exclusively user account specific. – Daniel Beck Sep 7 '12 at 18:44
