通过 SSH 挂起计算机后如何取回终端？

Question

我经常通过 SSH 连接到计算机只是为了让它进入睡眠状态。问题是当它休眠时，它会保持 SSH 连接打开（似乎是无限期的）。这是发生的事情：

oli@bert:~$ ssh tank
oli@tank:~$ sudo pm-suspend
[sudo] password for oli:

我输入我的密码，点击Return然后它挂起......直到我唤醒远程机器。

有什么方法可以在本地强制断开连接，这样我就可以取回我的终端，而不必关闭它并启动另一个？

输入 SSH 转义码！来自man ssh：

ESCAPE CHARACTERS
 When a pseudo-terminal has been requested, ssh supports a number of
 functions through the use of an escape character.

 A single tilde character can be sent as ~~ or by following the tilde by a
 character other than those described below.  The escape character must
 always follow a newline to be interpreted as special.  The escape
 character can be changed in configuration files using the EscapeChar
 configuration directive or on the command line by the -e option.

 The supported escapes (assuming the default ‘~’) are:

 ~.      Disconnect.

 ~^Z     Background ssh.

 ~&      Background ssh at logout when waiting for forwarded connection /
         X11 sessions to terminate.

所以：按Enter~.。
