如果 var == "yes" 在 bash

Question

我是 bash 的新手，我在 bash 教程中发现了一个名为 cal 的命令，想用 if

对其进行测试

代码如下：

    echo "What is your name?"
read PERSON
echo "Hello, $PERSON"
echo "Do you want to know the date?"
read CALENDAR
if [[ CALENDAR == "yes" ]]; then
  cal
else
  echo "Bye"
fi

所以你能帮我吗？当我运行它显示：

 bash main.sh
What is your name?
Tony #I input
Hello, Tony
Do you want to know the date?
yes #Also I input this
Bye

而且我也是新手我不知道 bash 但我知道 Python 所以不要告诉我我是否在 bash 中使用了 python

请帮助我运行。如果你想 Replit

，你可以运行

Answer 1

echo "What is your name?"
read PERSON
echo "Hello, $PERSON"
echo "Do you want to know the date?"
read CALENDAR
if [[ $CALENDAR == "yes" ]]; then
  cal
else
  echo "Bye"
fi

应该是if $var == "yes"
