I'm currently trying to run a script with 2 parameters which gets called via a BASH script. The script runs fine however the list of passed parameters , $ScriptCommandLine, always stays empty.

According to the wolfram website the list stays empty , "If the Wolfram Language kernel was run in a way other than via a WolframScript mechanism, the $ScriptCommandLine gives an empty list."

So the script has to use the interpreter #!/usr/local/bin/WolframScript -script. However the raspberry pi version of Wolfram/Mathematica does not have this executable! So i tried using the only executable i found, #!/usr/bin/wolfram -script which leads to the fact that $ScriptCommandLine stays empty.

Do i have to install something additional / Do i have to update something? Or is there any workaround (thought about writting the parameters in a textfile with bash and let the script import these )

  • $\begingroup$ The MathematicaScript executable is at the location /opt/Wolfram/WolframEngine/10.3/SystemFiles/Kernel/Binaries/Linux-ARM/MathematicaScript. But I cannot get it to work. It tells me error: The file /opt/Wolfram/WolframEngine/10.3/SystemFiles/Kernel/Binaries/Linux/WolframKernel is not found or is not executable. It is looking for WolframKernel at the wrong location. I don't know how to change that. $\endgroup$ – Szabolcs Feb 15 '16 at 20:45

    $\begingroup$ What's very interesting is that if I look into MathematicaScript (an executable binary), I find references to mash.c. That rings a bell! $\endgroup$ – Szabolcs Feb 15 '16 at 20:49

The wolframscript Wolfram Language script interpreter is now available on the Raspberry Pi and will set $ScriptCommandLine appropriately

pi@testpi3lx:~ $ wolframscript -code '{$Version, $ScriptCommandLine}'

{11.0.1 for Linux ARM (32-bit) (January 17, 2017), 
  {wolframscript, -code, {$Version, $ScriptCommandLine}}}
