命令文件：Expect + Title。我怎么能这样做？

Question

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

现在我用它：

#!/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

但是如何添加此

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

因为这不起作用

#!/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

您需要在expect脚本中使用tcl语法，而不是shell。你想要：

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

此外，您无需与rm -rf进行任何互动，因此请使用exec代替spawn：

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