pipes.go

package main

import (
	"io/ioutil"
	"os"

	"github.com/sirupsen/logrus"
)

func main() {
	fi, err := os.Stdin.Stat()
	if err != nil {
		logrus.Error("error reading from stdin")
		os.Exit(1)
		panic(err)
	}
	logrus.Infof("File Mode %s", fi.Mode())
	logrus.Infof("Os Mode Named Pipe %s", os.ModeNamedPipe)
	logrus.Infof("Operation %s", fi.Mode()&os.ModeNamedPipe)
	if fi.Mode()&os.ModeNamedPipe == 0 {
		logrus.Infof("No STDIN Input")
	} else {
		var data []byte
		data, err = ioutil.ReadAll(os.Stdin)
		if err != nil {
			logrus.Errorf("error reading from file %v", err)
		}
		logrus.Infof("There is STDIN '%s'", data)
