Using 'diskutil' to 'resetUserPermissions'

I am using a previous method to fix slow performance of my iMAC computer, but the 'string' diskutil resetUserPermissions /'id -u' now returns the following:

"Incorrect number of parameters

Usage: diskutil resetUserPermissions MountPoint|DiskIdentifier|DeviceNode UID

Reset the permissions of a user home directory.

Ownership of the affected disk is required."

How can I fix this ?

Have I used an incorrect 'string' regarding spaces and other characters?

What are the implications (security) if I just close the Terminal Box ?

Check out this article. From the example in the article the command uses back tics (found on the tilde "~" key) and not regular apostrophes around the "id -u" portion of the command. Compare them here:

`  back tic
'  normal apostrophe

So it should like like this:

diskutil resetUserPermissions / `id -u`

Thankyou HWTech, I now have the back slashes scrolling across the dialog box as I was expecting. All should be OK from this point forward. :)
