准备测试源码

main.go

package main

import "fmt"

func main()  {
	fmt.Printf("hello\n");
}

编译并运行

[yeqiang@localhost tmp]$ go build main.go
[yeqiang@localhost tmp]$ ll | grep main
-rwxrwxr-x. 1 yeqiang yeqiang 2025440 2020-08-11 16:52:25 main
-rw-rw-r--. 1 yeqiang yeqiang      68 2020-08-11 16:42:23 main.go
[yeqiang@localhost tmp]$ ./main
hello

查看输出文件信息
