This text in this section corresponds to the method described in [https://sourceforge.net/p/flightgear/mailman/message/36633375/ this message] on the <tt>flightgear-devel</tt> mailing list. It is more detailed, though, and should hopefully be easier to follow for non-experts. | This text in this section corresponds to the method described in [https://sourceforge.net/p/flightgear/mailman/message/36633375/ this message] on the <tt>flightgear-devel</tt> mailing list.

When a command should be run as an unpriviledged user, it will be preceded by a dollar sign: | |||
$ whoami | |||
toto | |||
In contrast, a hash sign (#) means that the command must be run with superuser privileges to achieve the desired effect: | |||
# whoami | |||
