英文:
What do three dots "./..." mean in Go command line invocations?
问题
如果你在Travis CI上运行Golang测试，它将使用三个点下载所有依赖项：
go get -d -v ./... && go build -v ./...
在这里，./...表示什么或者展开成什么？我做了一些研究，但似乎这不是Unix的惯例。
英文:
If you run Golang tests on Travis CI, it will download all of your dependencies with three dots:
go get -d -v ./... && go build -v ./...
What does ./... indicate or expand to there? I've done some research but it doesn't seem to be a Unix convention.

从命令go help packages中：
> 如果导入路径包含一个或多个“...”通配符，则它是一个模式，每个通配符都可以匹配任何字符串，包括空字符串和包含斜杠的字符串。这样的模式会扩展为在GOPATH树中找到的所有与模式匹配的包目录。作为特例，x/...匹配x以及x的子目录。例如，net/...会扩展为net及其子目录中的包。
英文:
From the command go help packages:
> An import path is a pattern if it includes one or more "..." wildcards,
each of which can match any string, including the empty string and
strings containing slashes. Such a pattern expands to all package
directories found in the GOPATH trees with names matching the
patterns. As a special case, x/... matches x as well as x's subdirectories.
For example, net/... expands to net and packages in its subdirectories.

你好！以下是翻译好的内容：
go [command] ./...
这里的<code>./</code>表示从当前文件夹开始，<code>...</code>表示递归向下。
**例如：**
go list ...
在任何文件夹中列出所有的包，包括标准库的包在前，然后是Go工作区中的外部库。

<summary>英文:</summary>
go [command] ./...
Here <code>./</code> tells to start from the current folder, <code>...</code> tells to go down recursively.
**For Example:**
go list ...
In any folder lists all the packages, including packages of the standard library first followed by external libraries in your go workspace.
