``sudo'' is a command commonly found in unix-like operating systems. It allows a normal user (without elevated rights on the system) to execute privileged commands. For example ``sudo make install'' execute the ``make install'' with administrator rights, so to say, so that a program install may take place.
``sudo make me a sandwich'' comes from the
excellent xkcd site (
http://xkcd.com/149/). One character asks the other to make him a sandwich, a request ignored at first. The character then asks again, but using the ``sudo'' command to get elevated privileges in asking for a sandwich, which seems to work.
