Deb软件包的许可证信息 [英] license info of a deb package

问题描述

我正在尝试获取已卸载的deb软件包的许可证信息.
dpkg --info <package-name>.deb没有提供该信息.
ubuntu中是否有任何命令可以提供此信息?
(在rpm世界中，rpm -qpi提供该信息)

I am trying to get license information of uninstalled deb packages.
dpkg --info <package-name>.deb does not give that information.
Is there any command in ubuntu which will give this info?
(In rpm world rpm -qpi gives that info)

推荐答案

我没有一个简单的命令.您可以执行以下操作:

There's no simple command that I know of. You can do something like this:

dpkg-deb --fsys-tarfile foo.deb |tar -xvO ./usr/share/doc/foo/copyright

这会将文件打印到标准输出.

This prints the file to standard output.

编辑嗯，听起来很难.快速浏览我的Debian系统上的apt缓存后，我发现了一些可能有用的短语:

Edit Hmm, that sounds hard. After a quick perusal of the apt cache on my Debian system, I found some phrases that might be useful:

• "GNU通用公共许可证"
• 上述版权声明和此许可声明"，请确保您先解开行

• "/usr/share/common-licenses/*"

这似乎是您最接近的标准许可证，但是请小心，因为 packaging 通常是在通用许可证下进行的，而软件包中的内容是在单独的许可证下进行的. /p>

^License: MPL-1.1 | GPL-2+ | Apache-2.0

This seems to be the closest to a standard license you'll get, but be careful since often the packaging is under a common-license, but the package contents are under a separate license.

但是，某些软件包(ImageMagick)仅在版权文件中具有自由格式的许可证，该许可证实际上并不符合任何股票许可证，只是有人认为它是DFSG批准的.

However, some packages (ImageMagick) simply have a free-form license in the copyright file that doesn't really conform to any stock license, except that someone considered it DFSG-approved.

Update 2012 :随着debian/copyright文件

Update 2012: This is beginning to change, as the debian/copyright file is now required to be machine-interpretable, so you can look forward to this in the future.
