使用 Expect 填写多行提示

Question

我正在尝试使用 Expect 来自动完成一些提示。提示之一，要求用户输入一些文本，然后按 CTR-D 保存文本或按 CTR-C 取消。我不确定，但我假设我试图自动完成的程序正在使用 cat 写入文件（如 cat > file.txt）。

Expect 似乎无法将文本发送到此多行提示符。当我执行时，出现“输入任务描述（^D 结束文本输入，^C 中止）：”行，然后它就挂起直到超时。有谁知道如何使用Expect做到这一点？

我的脚本：

#!/usr/bin/expect 

spawn tasks create

expect "Task assigned to (default=you): "
send "name\r"

expect "Enter a title: "
send "This is a test\r"

expect "Priority (default=wishlist): "
send "high\r"

expect "Comma-separated list of subscribers (default=None): "
send "None\r"

expect "Comma-separated list of task tags (default=None): "
send "None\r"

 expect "Enter task description (^D to end text entry, ^C to abort): "
 send "Description\r"
 send /004

结果：

[name@xxxx.xxx ~/createtasks] ./innerscript.exp
spawn tasks create
Task assigned to (default=you): name
Enter a title: This is a test
Priority (default=wishlist): high
Comma-separated list of subscribers (default=None): None
Comma-separated list of task tags (default=None): None
Enter task description (^D to end text entry, ^C to abort):
[name@xxxx.xxx ~/createtasks] 

看来这应该很简单...谢谢！

在脚本末尾添加：

set timeout -1    ;# wait for as long as necessary
expect eof        ;# for the spawned task to end.
