从 Debian 下载时有没有办法查询源文件的大小？

当我们跑步时apt，apt-get或者我们总是知道它的孩子aptitude需要多少空间（当然除外）。//home/$username

现在，当我们（在用户空间中）执行操作时，apt-get source在下载源文件之前无法知道源文件的大小，以免遇到任何最后一刻的意外。

我想分享一个真实的例子来描述这个问题。

二进制未知地平线未压缩时大约为 305 MB -

[$] aptitude show unknown-horizons

现在，如果我要下载源代码，它要么会下载整个 305 MB 或更多的未压缩包，要么只是下载/debian几乎没有 MB 或更多的目录。有没有办法做到这一点 ？

我猜它要么需要像apt-file这样的元数据 -

$ sudo apt-file update

答案1

您可以使用以下命令找出源 tarball 的大小apt-cache showsrc：

$ apt-cache showsrc unknown-horizons

请注意这些Files:条目：.origtarball（包含上游源代码）的大小为 188MiB，.debiantarball 的大小为 12KiB。这并没有告诉您提取 tarball 需要多少空间，但它给出了一些指示。

你能debian通过仅下载tarball 来仅下载目录.debian，无论是从源码包页面，或使用apt-get source --diff-only.
