How do you access ARGV in Mathematica?

Question

I would like to write command line scripts in Mathematica, but I cannot find the Argv[i_Integer] function Argv[i_Integer] . (FANTASTIC documents otherwise.)

Answer 1

$CommandLine works for Mathematica, MathematicaScript, MathKernel and math.

args.ma:

 #!/usr/bin/env MathKernel -script Print[$CommandLine] 

Example:

 $ ./args.ma abc {"MathKernel", "-script", "./args.ma", "a", "b", "c"} 

Answer 2

$ ScriptCommandLine seems to be the variable you will need for this, provided you use MathematicaScript for scripting . If you use math or MathKernel -script , this will be $ CommandLine .

Other relevant discussions: pretty old and one in the MMA toolkit .

Answer 3

I like to pass things when using environment variables:
