How to exit from ssh session created from bash script?
提问by user784637
I have the following bash script test.sh
我有以下 bash 脚本 test.sh
#!/bin/bash
ssh -o "StrictHostKeyChecking no" user@
#do some stuff
exit
However if I run this script ./test.shI need to enter ctrl+dto get out of the ssh session and it appears as if the exitcommand is not working the way I intended.
但是，如果我运行此脚本./test.sh，则需要输入ctrl+d才能退出 ssh 会话，并且该exit命令似乎没有按我预期的方式工作。
Is there any way I can exit this ssh session that was created from this bash script?

You may want to code a here document
您可能想对此处的文档进行编码
#!/bin/bash
ssh -o "StrictHostKeyChecking no" user@ << ENDHERE
here do some remote stuff
also here
exit
ENDHERE
If you code <<-ENDHEREthe initial spaces or tabs in each line of the here document are suppressed. Parameters (like $foo) are substituted unless you code <<\ENDHERE, and the ENDHEREcan actually be any word, conventionally in capitals.
如果您<<-ENDHERE对此处文档的每一行中的初始空格或制表符进行编码，则会被抑制。$foo除非您编码<<\ENDHERE，否则将替换参数（如），并且ENDHERE实际上可以是任何单词，通常为大写。
