Can Go Access the Initial Standard Input Stream?

In Go, Can You Access Initial Standard Input?

In Go, using os.Stdin to read from the original standard input should yield the desired results, as demonstrated by this code snippet:

package main

import "os"
import "log"
import "io"

func main() {
    bytes, err := io.ReadAll(os.Stdin)

    log.Println(err, string(bytes))
}

When you execute echo test stdin | go run stdin.go, the program should print test stdin without issues.

If you encounter errors, providing the code you used will greatly help in identifying the problem.

For handling line-based input, you can utilize bufio.Scanner:

import "os"
import "log"
import "bufio"

func main() {
    s := bufio.NewScanner(os.Stdin)
    for s.Scan() {
        log.Println("line", s.Text())
    }
}
