    test        test packages
    tool        run specified go tool
    version     print Go version
    vet         run go tool vet on packages

Use "go help [command]" for more information about a command.

Additional help topics:

    c           calling between Go and C
    filetype    file types
    gopath      GOPATH environment variable
    importpath  import path syntax

PS D:\go_code>

go get，获取远程包，需要原装：git、hg
go run，运行程序
go build，测试编译，是否有编译错误
go fmt，格式化源码，部分IDE在保存时会自动的调用
go install，编译包文件并编译整个程序
go test，运行测试文件
go doc，查看文档，CMM手册

Eg：godoc

PS D:\go_code> godoc fmt Println
func Println(a ...interface{}) (n int, err error)
    Println formats using the default formats for its operands and writes to
    standard output. Spaces are always added between operands and a newline
    is appended. It returns the number of bytes written and any write error
    encountered.
