How to Redirect Debug Logs to Standard Error in Go?

Redirecting Debug Logs to Standard Error in Go

To output custom debug logs to stderr, allowing them to be easily differentiated from existing verbose logs, consider the following methods:

• Creating a Dedicated Logger:

  <code class="go">l := log.New(os.Stderr, "", 1)
  l.Println("Log message")</code>

  Copy after login

• Utilizing fmt.Fprintf:

  <code class="go">fmt.Fprintf(os.Stderr, "Log message: %s", str)</code>

  Copy after login

• Writing Directly to os.Stderr:

  <code class="go">os.Stderr.WriteString("Log message")</code>

  Copy after login

By choosing one of these options, you can effectively isolate your debugging logs to stderr, making it convenient to view them separately.
