Go – How to create file in go

Here, We will see how to create file in go. We can do it by using Create() function in os package in go golang.

Function prototype:

func Create(name string) (*File, error)

Input Parameter:

name : file name

Create() function creates the named file. If the file already exists, it is truncated. By default, It creates file with mode 0666 (before umask).

Return value:

Create() function in os package returns 
the file pointer.

If there is an error, it will be of type 
*PathError.

Example with code:

package main

import (
  "fmt"
  "os"
 "log"
)

func main() {

  file_name := "/Users/hello.go"

  file, err := os.Create(file_name)

  if err != nil {

    log.Fatal(err)

  }

  fmt.Println("File Pointer: ", file)

  file.Close()
}

Output:

$ sudo go run sample.go
File Pointer: &{0xc000050180}

$ ls -lrt hello.go
