It's a silly interface, but also a long and hallowed UNIX tradition,

Thanks Robert. I have read the man page for getopt_long and optind. they are in the same man page.
but i still could not understand why optind always equal to 1 when I gdb initdb and print optind?
Was optind supported to increased after getopt_long pasered every parameter?
