To run X-Plane using command-line arguments, you must launch X-Plane using terminal.
- Open the utility "Terminal"; it can be found in the Utilities folder (within the Applications folder). Terminal gives you a command-prompt.
- Drag your X-Plane application into the terminal window. The command line will list the names of all of the folders leading to your copy of X-Plane using / for directories. All spaces will be preceded by \ characters.
- Delete the extra space at the end and add the following to the command-line:
- After the word X-Plane you can include command-line options.
This would launch X-Plane 850 RC-3 (in the X-Plane 850 folder of my hard drive "GIS") using the --no_sprites option./Volumes/GIS/X-Plane\ 8.50\ RC-3/X-Plane\ 850\ RC-3.app/Contents/MacOS/X-Plane --no_sprites
To Lauch X-Plane from a DOS prompt you will have to...
- Pick "Run..." from the Start menu. Type cmd (3 letters) for the name of the program and press return. This will open up a DOS prompt.
- Type cd and a space and then drag your X-Plane folder into the DOS prompt window (the full path of the file will be typed). Press return. This will move your command prompt to the X-Plane directory.
- Drag the X-Plane application into the DOS prompt window. You will see its full name in quotes including the hard disk and directories separated by back-slashes.
- You can then add any additional command-line options.
(It is necessary to change directories on Windows to make sure that Log.txt and other files are put in the right place. On Mac these files always end up in the X-System directory.)"X-Plane 850 RC-3.exe" --fps_test=1
X-Plane can be launched like any other command-line tool; you may need to prefix it with ./ if you don't have the current working directory in your search paths. For example:
On my distribution (Ubuntu with GNOME, stop your snickering!) it is not possible to simply drag the application into a terminal because the spaces in the file paths will not be properly escaped.cd /home/bsupnik/X-Plane\ 8.50\ RC-3/
LD_PRELOAD=/usr/lib/libalut.so ./X-Plane-i586 --fps_test=1 --require_fps=20
Command Line Options
Generally X-Plane command line options have full names and two dashes. Some require parameters, as in =1. Order does not matter and you can use as many options as you want. Some examples (simplifying the application name, which varies by version and OS):
Rather than document the options here, use the --help option to list all command-line options in the current version of X-Plane.X-Plane --no_sprites
X-Plane --fps_test=2 --no_pixel_counters
Some Typical Examples
A number of drivers crash when X-Plane uses VBOs, particularly on Linux. If you can run every application except X-Plane itself, you may want to try:
Some drivers cause texture corruption when hardware-accelerated runway lights are used; you can work around this with:X-Plane --no_vbos
EDIT: the Windows version won't show the --help string in the DOS window by default, but StormRunner pointed out to me that you can do this:X-Plane --no_sprites
which routes the output to the DOS window."X-Plane.exe" --help | more
