Question

我有shell脚本测试有以下内容：

read -s -n 1 -p "press enter to continue..." key
if [[ $key = "" ]]; then
    echo 'You pressed enter!'
else
    echo "You pressed '$key'"
fi

我用以下脚本调用上面的脚本。但是当我执行下面的脚本然后它挂起在输入级别

#!/bin/bash
/usr/bin/expect <<EOF
spawn ./test.sh
expect "Press enter to continue..."
send "\r"
EOF

解答：您忘记了if语句中的then。

顺便说一句：
您可以像这样使用REPLY变量：

#!/bin/bash
read -r -n 1 -p "press enter to continue..."
if [[ $REPLY = "" ]] ; then
    echo 'You pressed enter!'
else
    echo "You pressed '$REPLY'"
fi

如果在调用shell脚本后使用，则Expect无效
