Go 的常用命令

Go

go env: 打印go的环境信息
go fmt: 运行gofmt对go代码进行格式化
go build: 编译包和依赖
go run: 编译并运行go程序
go version: 显示go程序的版本
go help: 打印命令的帮助信息
go get: 下载并安装包和依赖（-v 显示操作流程的日志及信息；-u 下载丢失的包，但不会更新已经存在的包）

Here's an example directory layout:

    GOPATH=/home/user/go

    /home/user/go/
        src/
            foo/
                bar/               (go code in package bar)
                    x.go
                quux/              (go code in package main)
                    y.go
        bin/
            quux                   (installed command)
        pkg/
