我想自动安装一个Youtube内置的SDK。它提供了一个用于安装的shell脚本，但shell脚本需要用户输入，我想自动化。我尝试将以下内容添加到现有的shell脚本中，以自动安装SDK：

...
        echo "built SDK, install SDK"
        /usr/bin/expect -c '
                spawn /path/to/SDK/install/script.sh
                expect "Enter target directory for SDK (default: /opt/poky/3.1.5): \r"
                send -- "\r"
                expect "You are about to install the SDK to "/opt/poky/3.1.5". Proceed [Y/n]? \r"
                send -- "\r"
        '
        /bin/bash

但这是我运行时得到的结果：

Poky (Yocto Project Reference Distro) SDK installer version 3.1.5
=================================================================
Enter target directory for SDK (default: /opt/poky/3.1.5): extra characters after close-quote
    while executing
"expect "You are about to install the SDK to "/"
$

我不知道额外的字符错误来自哪里，有人能帮忙吗？

你已经在一个双引号字符串中放入了双引号：

expect "You are about to install the SDK to "/opt/poky/3.1.5". Proceed [Y/n]? \r"
# .....^....................................^...............^...................^

你得躲开他们

expect "You are about to install the SDK to \"/opt/poky/3.1.5\". Proceed [Y/n]? \r"
# ..........................................^................^

此外，Tcl/expect中的[brackets]是命令替换语法，因此一旦双引号问题得到解决，您可能会看到invalid command name "Y/n"
正确的解决方案是使用Tcl的非插值引用机制：牙套

expect {You are about to install the SDK to "/opt/poky/3.1.5". Proceed [Y/n]? }
# .....^......................................................................^

参见http://www.tcl-lang.org/man/tcl8.6/TclCmd/Tcl.htm了解Tcl语法规则。
