Bash脚本执行exec adb卸载命令后提前退出，无法执行后续逻辑

嘿，你遇到的这个问题核心是**exec命令的使用方式不对**！

为什么脚本会提前退出？ #

exec命令的作用是用指定的程序替换当前的shell进程——也就是说，当你执行exec adb uninstall...时，你的脚本进程直接被adb命令替换了，adb执行完成后，这个进程就结束了，自然没办法回到脚本继续执行后面关于Google Duo的逻辑。

怎么解决？ #

很简单，把所有的exec去掉就行！直接执行adb命令，它会在脚本的子进程中运行，执行完毕后会回到脚本继续往下走。

另外我还发现脚本里有个小笔误：read -p "Would you like to delete Google Duo? (yes/no) " DUO#里的#是多余的，会导致变量名异常，我也一起帮你修正了。

修改后的完整脚本如下：

#!/bin/bash
read -p "Would you like to delete Google Drive? (yes/no) " DRIVE
if [ "$DRIVE" == "yes" ]
then
    echo "Google Drive will be deleted."
    adb uninstall --user 0 com.google.android.apps.docs
elif [ "$DRIVE" == "no" ]
then
    echo "Google Drive will not be deleted."
else
    echo "It's a yes or no question!"
fi
read -p "Would you like to delete Google Duo? (yes/no) " DUO
if [ "$DUO" == "yes" ]
then
    echo "Google Duo will be deleted."
    adb uninstall --user 0 com.google.android.apps.tachyon
elif [ "$DUO" == "no" ]
then
    echo "Google Duo will not be deleted."
else
    echo "It's a yes or no question"
fi
