命令文件：预期+标题。我怎样才能做到这一点？

Question

如何使用expect和title执行命令文件（macOS）或类似的（GNU/Linux）？

现在我用这个：

#!/usr/bin/expect -f 

set timeout -1 

spawn rm -rf /path/to/.ssh/known_hosts 

spawn ssh username@IP 
expect "?" 
send "yes\r" 
expect "assword:" 
send "thepassword\r" 
expect "thenamemachine:~#" 
send "bash <(curl -s aFile.sh)\r" 
interact 

但我怎么可以添加此

title='My first title' 
echo -n -e "\033]0;$title\007" 

因此不起作用

#!/usr/bin/expect -f 

title='My first title' 
echo -n -e "\033]0;$title\007" 

set timeout -1 

spawn rm -rf /path/to/.ssh/known_hosts 

spawn ssh username@IP 
expect "?" 
send "yes\r" 
expect "assword:" 
send "thepassword\r" 
expect "thenamemachine:~#" 
send "bash <(curl -s aFile.sh)\r" 
interact 

Answer 1

您需要使用tcl语法期望脚本，而不是shell。你想：

set title "My first title" 
send_user "\033]0;$title\007" 

而且，你不需要有任何rm -rf互动，所以使用exec代替spawn：

exec rm -rf /path/to/.ssh/known_hosts
