<p>Hi I’m a noob at golang and would like to know how you create a golang application that asks for your input you type it in console and it puts in a text file. Thanks </p>

<p>Write to file - <a href="https://golang.org/pkg/io/ioutil/#WriteFile" rel="nofollow">https://golang.org/pkg/io/ioutil/#WriteFile</a></p>
<p>You need to write some plumbing logic to join them together.</p></pre>msubramm5: <pre><pre><code> package main
import (
"bufio"
"fmt"
"os"
"io"
)
func main() {
scanner := bufio.NewScanner(os.Stdin)
file, err := os.Create("abc.txt")
defer file.Close()
if err != nil {
fmt.Printf("Error creating file:%s", err.Error())
} else {
for scanner.Scan() {
io.WriteString(file, scanner.Text())
}
if err := scanner.Err(); err != nil {
fmt.Fprintln(os.Stderr, "Error reading standard input:", err.Error())
}
}
}
