在ssh中,输入[Enter][~][.]这三个键会直接退出当前连接。
由一次断网了,当前终端中的ssh连接不管输入什么都没有响应。由于情况特殊,所以不能直接关闭终端。你可以直接使用kill命令结束ssh连接。也可以使用ssh的转义字符。
当终端里的ssh连接没有响应时,可以依次输入[Enter][~][.],ssh会主动退出。即使终端里的ssh连接由响应,使用该按键序列也可以退出ssh,但是我们通常使用Ctrl + D组合键来退出。
所有的转义字符序列
下面是由ssh支持的转义序列,详细的内容可以查看man手册或者官方文档:
ESCAPE CHARACTERS
When a pseudo-terminal has been requested, ssh supports a number of
functions through the use of an escape character.
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.
~# List forwarded connections.
~& Background ssh at logout when waiting for forwarded connection
/ X11 sessions to terminate.
~? Display a list of escape characters.
~B Send a BREAK to the remote system (only useful if the peer sup‐
ports it).
~C Open command line. Currently this allows the addition of port
forwardings using the -L, -R and -D options (see above). It
also allows the cancellation of existing port-forwardings with
-KL[bind_address:]port for local, -KR[bind_address:]port for
remote and -KD[bind_address:]port for dynamic port-forwardings.
!command allows the user to execute a local command if the
PermitLocalCommand option is enabled in ssh_config(5). Basic
help is available, using the -h option.

~V Decrease the verbosity (LogLevel) when errors are being written
to stderr.
