🤔 Which comment style should I use in batch files?

Are you confused about which comment style to use in batch files? 🤷‍♂️ Don't worry, you're not alone! 💡 In this blog post, we will explore the two commonly used comment styles in batch files and discuss when and how to use them effectively. Let's dive in! 🚀

The REM command: Traditional and reliable 🖋️

The first comment style you may have come across is the good old REM command. This command has been around since the early days of batch scripting, and it is widely supported on all versions of Windows. 😎

Using REM is straightforward. All you need to do is prefix your comments with the REM command, like this:

REM This is a comment explaining what the code does

The REM command is reliable and commonly used in many batch scripts and examples you find online. It provides a clear indication that the line is a comment and won't be executed by the batch interpreter. ✔️

Double-colon (::) comments: A neat alternative 📝

Now, let's talk about the alternative comment style using double colons (::). This style may not be as widely known or used as the REM command, but it has its advantages. 🤔

Double-colon comments are processed differently than REM comments. They are considered labels by the batch interpreter and are processed before any redirection symbols. This distinction means that double-colon comments are sometimes preferred over REM comments when working with redirection or labels. 👀

To use double-colon comments, simply prefix your comments with double colons, like this:

:: This is a comment using double colons

It's important to note that double-colon comments are not supported on all versions of Windows. Although they work on most modern systems, if you plan to distribute batch files across various Windows versions, it's safer to stick with the reliable REM command. ✔️

So, which comment style should you use? 🤷‍♀️

It all depends on your specific requirements and target audience. While the REM command is universally supported, double-colon comments offer more flexibility in certain situations, especially when dealing with redirection or labels. 🤓

If you are writing batch files for personal use or within a controlled environment, using double-colon comments can be a neat and concise way to annotate your code. Just ensure that you are aware of the potential compatibility issues on older Windows systems. 🕵️‍♂️

On the other hand, if you are creating batch files for general distribution or compatibility over a wide range of Windows versions, playing it safe with the traditional REM command is the way to go. It may not be as fancy, but it guarantees your comments will be understood across the board. ✔️
