Binary version clarification

[mertssmnoglu]

Enhancement

We need to know the version of the binary by using a command like capture --version. Without knowing the exact version of capture, we cannot be 100% certain about its behavior.

It's very important for troubleshooting.

How to implement?

package main

import (
	"flag"
	"fmt"
	"os"
)

var version = "develop" // We can modify the version variable on the compile time using go build flags

func main() {
	showVersion := flag.Bool("version", false, "Display the version of the capture")
	flag.Parse()

	// Check if the version flag is provided
	if *showVersion {
		fmt.Printf("capture version: %s\n", version)
		os.Exit(0)
	}
	// rest of it
}
