Elevated permissions

Some commands need a higher level of access to run. If this is the case, you can prefix the command you run with sudo</span>. For example, sudo ls</span>, rather than just ls</span>.

Be very careful about using sudo. Any command you run with it will be able to do whatever it likes to your computer. Any mistakes you make, for example in deleting or moving files, could have very drastic outcomes if you run it with sudo. It should be very uncommon that you need to use it.
