Try this: Do a search for "Terminal" in the search bar and select the Desktop search. Click the find button to get the list of matches, then look towards the bottom of the list and you should see Terminal in /usr/bin. Right click on it and select open to open a terminal.

 

thanks i got that up now what command should i type any ideas?
