Other operations

Read and write are not the only operations that can be executed on a file. In the following section, we'll look at how to use them using the os package.

Create

In order to create an empty file, we can call a helper function called Create, which opens a new file with a 0666 permission and truncates it if it doesn't exist. Alternatively, we can use OpenFile with the O_CREATE|O_TRUNCATE mode to specify custom permissions, as shown in the following code:

package main

import "os"

func main() {
    f, err := os.Create("file.txt")
    if err != nil {
        fmt.Println("Error:", err)
        return
    }
    f.Close()
}
