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 ?
