Of course, it's always possible to make commands shorter by setting up aliases (see tips at the end of [https://sourceforge.net/p/flightgear/mailman/message/36634426/ this message]) or by adding the directory containing the program to your <tt>PATH</tt>. But in the specific case of <tt>download_and_compile.sh</tt>, since it should most of the times be be run from the same directory (noted ''$dir'' in this document, see below), adding it to the <tt>PATH</tt> is not really advised. | Of course, it's always possible to make commands shorter by setting up aliases (see tips at the end of [https://sourceforge.net/p/flightgear/mailman/message/36634426/ this message]) or by adding the directory containing the program to your <tt>PATH</tt>.
