rdesktop用法

rdesktop [options] server[:port]

       -u
              Username for authentication on the server.
       -d
              Domain for authentication.
       -s
              Startup  shell  for  the  user  -  starts a specific application instead of Explorer.
       -c
              The initial working directory for the user.  Often used in  combination with -s to set up a fixed login environment.
         -p
              The  password  to authenticate with.  Note that this may have no effect if "Always prompt for password" is enabled on the server.WARNING: if you specify a password on the command line it may be visible to other users when they use tools like ps.  Use -p - to
make  rdesktop  request  a  password  at  startup (from standard
input).
       -n
              Client hostname.  Normally rdesktop  automatically  obtains  the hostname of the client.
       -k
              Keyboard  layout  to  emulate.   This  requires  a corresponding keymap file to be installed.  The standard keymaps provided with rdesktop  follow the RFC1766 naming scheme: a language code followed by a country code if necessary - e.g.  en-us,  en-gb,  de, fr, sv, etc.  The default is en-us (a US keyboard).
    -g
              Desktop   geometry  (WxH).  If  geometry  is  the  special  word "workarea", the geometry will be fetched from the extended  window  manager hints property _NET_WORKAREA, from the root window.The geometry can also be specified as a percentage of the  whole screen, e.g. "-g 80%".
       -f     Enable  fullscreen  mode.  This overrides the window manager and causes the rdesktop window to fully cover  the  current  screen.Fullscreen mode can be toggled at any time using Ctrl-Alt-Enter.
       -b     Force the server to send screen updates as bitmaps  rather  than using higher-level drawing operations.
       -B     Use  the  BackingStore  of the Xserver instead of the integrated one in rdesktop.
       -e     Disable encryption.  This option is only needed (and  will  only work) if you have a French version of NT TSE.

       -E     Disable  encryption  from  client  to  server.   This  sends  an encrypted login packet, but everything after this is unencrypted (including interactive logins).
       -m     Do not send mouse motion events.  This saves bandwidth, although some Windows applications may rely on receiving mouse motion.
       -C     Use private colourmap.  This will improve colour accuracy on  an 8-bit display, but rdesktop will appear in false colour when not focused.

       -D     Hide window manager decorations, by using MWM hints.

       -K     Do not override window manager key bindings.  By default  rdesktop attempts to grab all keyboard input when it is in focus.

       -S
              Enable  single  application  mode.  This option can be used when running a single, maximized application (via -s). When the minimize  button of the windows application is pressed, the rdesktop
window is minimized instead of the remote application. The maximize/restore  button  is  disabled.  For  this to work, you must
specify the correct button size, in  pixels.  The  special  word
"standard" means 18 pixels.
