I usually use global variable call arguments, which is an array can be used for passing arguments to the jsx file when I execute a script from command line, but extendscriptr outputted file can't be used for doing this, when I log this variable I got a function....
Then I came up with a quick solution, that is I put single line at top of outputted file with

var scriptArgs = arguments;

and I can access my command line arguments correctly with scriptArgs.
Dose anybody has better solution?
