Java Beanshell scripting with args[] to the the program?

The Beanshell documentation implies that you can run a script using this format on the command line:

java bsh.Interpreter script.bsh [args]

The only problem with this is that I cannot get it to work. I know how to call other scripts with args from a Beanshell script but I cannot get the initial script to take args. Help?

For example, a beanshell script like this one, wont parse the args:

import java.util.*;
for (int i=0; i < args.length; i++) {
  System.out.println("Arg: " + args[i]);
}

Also, this doesn't work either:

import bsh.Interpreter;
for( i : bsh.args )
System.out.println( i );
Solution

  • The command-line arguments are available under bsh.args, not args. So if you change all instances of args in your code with bsh.args, you should be good to go. Reference: Special Variables and Values.

    This worked for me:

    for (arg : bsh.args)
    print(arg);

    Example:

    $ bsh foo.bsh 1 2 3
1
2
3
