如何让我的 shell 脚本自动接受提示？

我制作了一个简单的 shell 脚本（以 root 身份运行）来下载每次重新安装 ubuntu 时可能需要的基本应用程序：它看起来像这样：

apt-get install docky && apt-get install geany && apt-get install firefox && apt-get install audacity && apt-get install kdenlive && apt-get install openshot && apt-get install shotwell && apt-get install stellarium && apt-get install thunderbird, etc...

问题是我仍然会收到 Y/n 提示，并且我需要一直手动按 Y。有没有办法可以自动接受所有提示并下载和安装所有内容？

答案1

使用魔法。

如果您缺少魔法，请尝试向 apt-get 传递一些参数。-y应该会有所帮助。它会提前告诉 apt-get 您将对确认提示说“是”。

apt-get install -y docky geany firefox audacity kdenlive openshot shotwell stellarium thunderbird

要查看 apt-get 可以和不可以执行的操作列表，请man apt-get在终端中输入 并点击Enter。您也可以使用任何其他命令执行此操作。例如，man sudo或man nano，甚至man chromium-browser。

答案2

您可以简单地在同一个命令中列出要安装的多个包。我相信这也会只给您一个 y/n 提示。示例：

sudo apt-get install docky geany firefox

答案3

我过去发现，如果其中一个命令出现“故障”，以这种方式将命令串在一起就会导致问题。

例如，如果您的命令类似于此：

sudo apt-get install 1 2 3 4

然后，如果程序 3 出现错误，则不会安装 4。将它们分开放在每行上可以解决这个问题。如果出现错误，脚本将继续运行。

这是我用于新安装的脚本示例：

echo "Please run this in an empty folder. Failure to do so may cause data loss!"
read -p "Press ENTER to continue, or close the window to abort."

echo " "
echo "Now backing up the sources list."
