我试着这样创建bash脚本：

#!/bin/bash

echo "Where are you now?"
read $city

if [[ $city == "Kyiv" ]] && [[ $city == "Berlin" ]] && [[$city == "California"]];
then
        case $city in
        Kyiv)
        echo "Ukraine";;
        Berlin)
        echo "Germany";;
        California)
        echo "USA"
  esac

else
        echo  "$city Its not the city"
fi

字符串
并始终输出：
第一个月
我检查了很多文档，但找不到问题。
还有，
尝试使用不带“case”的条件语句：

#!/bin/bash

echo "Where are you now?"
read $city
if [[ $city == "Kyiv" ]]
then
        echo "Ukraine"
elif [[ $city == "Berlin" ]]
then
        echo "Germany"
elif [[ $city == "California" ]]
then
        echo "USA"
else
        echo " $city Its not the city"
fi

型
但输出相同：
It’s not the city个
