Getting file information

If you need to discover basic information about the accessed file, Go's standard library provides a way on how you can do this. This recipe shows how you can access this information.

How to do it...

1. Open the console and create the folder chapter06/recipe01.
2. Navigate to the directory.
3. Create the sample test.file with the content This is test file.
4. Create the fileinfo.go file with the following content:

        package main

        import (
          "fmt"
          "os"
        )

        func main() {

          f, err := os.Open("test.file")
          if err != nil {
            panic(err)
          }
          fi, err := f.Stat()
          if err != nil {
            panic(err)
          }

          fmt.Printf("File name: %v\n", fi.Name())
          fmt.Printf("Is Directory: %t\n", fi.IsDir())
          fmt.Printf("Size: %d\n", fi.Size())
          fmt.Printf("Mode: %v\n", fi.Mode())

        }

5. Execute the code by running go run fileinfo.go in the main Terminal.
