       fgfsrc - FlightGear command-line options file


       fgfsrc  is a file containing command-line options read by fgfs(1) at startup. This file is
       meant for those people who do not use a graphical launcher to run the simulator,  so  that
       they will be able to specify most preferences that do not change often there (for example,
       custom scenery/aircraft locations or screen  size  options),  and  only  those  frequently
       modified (like the starting airport) on the command line.

       The  file  must  be  in  plain-text  format and ASCII-encoded. It must contain one or more
       command-line options listed in fgfs(1); each option must be given on a separate line.

       If the first non-whitespace character in a line is an octothorpe (#), fgfs(1)  treats  the
       line  as  a  comment and ignores it. Comments should not be added after an option, because
       that might cause the simulator to fail under some conditions (notably, when  the  command-
       line argument given on the line is of the form --prop=).

       Variables in paths, like $HOME or $FG_HOME, are not expanded.


       ~/.fgfsrc.hostname, ~/.fgfsrc
           Configuration files containing command-line options for fgfs(1).  The simulator parses
           command-line arguments first, then ~/.fgfsrc.hostname (where hostname is the  hostname
           of the machine) and then ~/.fgfsrc, if they exist, in that order.


       The  following  example configuration file synchronizes the simulator clock with the local
       real-world time, loads real-world weather data, sets  the  window  size  to  1024x768  and
       enables random scenery objects and AI traffic:
