Hi
I have opened two files and want to use *io.Copy* to read from one file and
write to another, but it does not work.
If I close first file and then reopen it* io.Copy* will work correctly.Can
anybody please help on this issue?
f1, err := os.Create("File1.txt")
> checkErr(err, "Error creating File1.txt")
> // defer f1.Close()
>
> f2, err := os.Create("File2.txt")
> checkErr(err, "Error creating File2.txt")
> defer f2.Close()
>
> c1, err := f1.WriteString("Hello Pipe!")
> checkErr(err, "Error writting to File1.txt")
> fmt.Println("Written Count - f1: ", c1)
>
> err = f1.Sync()
> checkErr(err, "Error writting File1.txt to disk.")
>
> // f1.Close()
> // f1, err = os.OpenFile("File1.txt", os.O_RDWR, 0664)
> // defer f1.Close()
> // checkErr(err, "Error opening File1.txt again.")
>
> c2, err := io.Copy(f2, f1)
> checkErr(err, "Error copying File1txt to File2.txt.")
> fmt.Println("Written Count - f2: ", c2)
>
Thanks
