China DOS Union

I haven't been using DOS for very long, and I've read quite a few articles introducing batch files, but none of them explain it in enough detail. I'd like to ask the experts here how I should study this and how to understand it. Please give me some guidance, thanks!

Practice is the only standard for testing truth. After you understand the functions and basic usage of some basic batch commands, try modifying some already completed batch files and see what changes before and after the modification. Then combine that with the command's own help information to better understand what the command does.
That's how I learned it.

Thanks, I'll improve by working through some examples. But right now I want to know which commands can be used in batch files.

All commands and executable files in the search path—as long as you can type them at C:\>—can be used in a bat file.

bat also has its own special commands, such as if errorlevel and so on.

I see, but I tried making a few and still feel it's rather difficult.
