Go exec.Command example

exec.go

package main

import (
	"bytes"
	"fmt"
	"os/exec"
	"strings"
)

func main() {
	//	Split the entire command up using ' -' as the delimeter
	parts := strings.Split(`pushnotify.exe --to=gqukgkJyLtchaLE41WUEJ2qFM7Q3tb --title=New Plex content --message={showname} season {showseasonnumber} episode {showepisodenumber} just landed on Plex --sound=magic`, " -")

	//	The first part is the command, the rest are the args:
	head := parts[0]
	args := parts[1:len(parts)]

	//	Format the command
	cmd := exec.Command(head, args...)

	/*
		//	Sanity check -- just print out the detected args:
		for _, arg := range cmd.Args {
			log.Println(arg)
		}
	*/

	//	Sanity check -- capture stdout and stderr:
	var out bytes.Buffer
	var stderr bytes.Buffer
	cmd.Stdout = &out
	cmd.Stderr = &stderr

	//	Run the command
	cmd.Run()

	//	Output our results
	fmt.Printf("Result: %v / %v", out.String(), stderr.String())

}

Thanks for sharing

A default use case perhaps is connecting stdout and stderr to the related os files, like so :

cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr

//	Run the command
cmd.Run()
