fgfsrc - FlightGear command-line options file
is a file containing command-line options read by fgfs
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 ( #
(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
, 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:
