Как авторизоваться в ssh по паролю в bash скрипте без использования expect?

     SSH_ASKPASS           If ssh needs a passphrase, it will read the
                           passphrase from the current terminal if it was run
                           from a terminal.  If ssh does not have a terminal
                           associated with it but DISPLAY and SSH_ASKPASS are
                           set, it will execute the program specified by
                           SSH_ASKPASS and open an X11 window to read the
                           passphrase.  This is particularly useful when call‐
                           ing ssh from a .xsession or related script.  (Note
                           that on some machines it may be necessary to redi‐
                           rect the input from /dev/null to make this work.)
