While I don't expect any nefarious commands from you, I still don't like 
to run an unknown command as root on my main machine. Therefore I tried 
it with an Xubuntu 13.04 Live-CD and this is the result:

xubuntu at xubuntu:~$ sudo su
root at xubuntu:/home/xubuntu# 
Components.classes["@mozilla.org/browser/nav-history-
service;1"].getService(Components.interfaces.nsPIPlacesDatabase).DBConnection.executeSimpleSQL("VACUUM");
bash: syntax error near unexpected token 
`Components.interfaces.nsPIPlacesDatabase'
root at xubuntu:/home/xubuntu# 

Obviously there is something wrong with the command ...

I suppose it is a command to be run within a database program (sqlite?), 
but I'm not familiar with any of them, so I don't even know if that is a 
wrong guess.
