Numlock Key

I am trying to set the numlock on during bootup. I found an article on the SDB and got to the last step and got lost. It says "copy this file into the cirectory /usr/local/bin and make an entry in the file ~/.xinitrc." It does not give the syntax for doing this. I would suppose it would go into the "# Add your own lines here..." section. Would anyone have input on what the syntax should be to add the /usr/local/bin/setnumlock to this file?
