    It's probably a bad idea to let the user enter a visible password. That said, suggest that the user quote the password or escape special characters, noting that in some shells, some characters are ridiculously difficult to quote correctly.

    Also search here and elsewhere. A quick search turned up Inputting a password w/o having it displayed on screen, which may help.

      What is the cmd interpreting & as?

        & means "run the preceding command in the background". So, for example,
        ./myprogram username lsrkj&etk
        will attempt to first run the command ./myprogram username lsrkj as a background process and then, while that's running, also run the command etk in the foreground (probably producing the error "etk: command not found").
