Executing command line options
Can someone please tell me how to modify/add to this code so that it recognizes UNIX command options (all beginning with "-") and executes the command with options?



Code:
#include<stdio.h>
#include<stdlib.h>

int main(int argc, char *argv[])
{

     int i;

    system("stty -echo");

    for(i=1; i<argc; i++)
    {
        printf("The command %s is executed.\n", argv[i]);
        system(argv[i]);
     }

    system("stty echo");
    return 0;
}

binfmtgcj-interpreter

binfmtgcj(1)							     binfmt_C							      binfmtgcj(1)

NAME

       binfmtgcj-interpreter - binfmt_misc gcj handler

SYNOPSIS

       binfmtgcj-interpreter GCJ-java-source-file-name [command-line opions ...]

DESCRIPTION

       binfmtgcj-interpreter compiles a Java source file specified on the command-line using the GCJ compiler, and executes the resulting file.

       It  is  designed  to be used as a handler for binfmt_misc handler, which is a system used in Linux for handling arbitrary files as executa-
       bles.

       The command-line options are passed on to the compiled binary.

FILE MAGIC

       There is a requirement for C source files to have the magic characters //BINFMTGCJ: at the beginning of the file.

       That line also is used to specify the additional command-line options for C compiler.

ENVIRONMENT

       GCJ    The compiler used.  The default is to use gcj

       BINFMTCTMPDIR

	      Temporary directory used for binary and execution.

	      Falls back to $TMPDIR $TEMPDIR or /tmp

       BINFMTC_DEBUG
	      enables debug output if set.

       BINFMTC_GCJ_OPTS
	      Additional GCJ options.  Use BINFMTC_DEBUG to verify the options being passed on to gcc.

	      The default is  -O2 -Wall
