1、获取文件属性
示例：
get_file_attribute.go
package main
import (
"fmt"
"os"
)
func main() {
list := os.Args
if len(list) != 2 {
fmt.Println("useage: xxx file")
return
}
fileName := list[1]
info, err := os.Stat(fileName)
if err != nil {
fmt.Println("err = ", err)
return
}
fmt.Println("name = ", info.Name())
fmt.Println("size = ", info.Size())
}
执行结果：
