Repeat a cmd command

Hello,

There are different ways to create an infinite loop in a batch file, including the one that was mentioned, and we don't see why it wouldn't work:

We don't really see the point of looping a DIR command whether it's colored or not (there are also other ways to color all or part of the console), but if you don't publish your exact code, it will be hard to discuss "it's not working" without further details.

Yes, but if we don't have, like all of us, the tech-savvy fiber, we can write:

color a dir/s :begin goto begin

especially if we type it each time in a CMD window, not with a batch file.

No, you need to put dir /s after the label :begin.

I'm not sure that branching instructions are only read in a batch file and not at the command line, that's another question.

Yes, of course, it was an example of code to illustrate an error that someone with little experience might write if they are not given the complete code.

Hello!

It works for me, I can color the console well, but our friend Ssio wants to color his screen, what adjustment to the command then?

Hello,

We're mixing genres.

The DIR command will not concern the wallpaper but only the console; we don't see the point of repeating it, but if we have to do it not in a batch but directly in the command line, the redirection labels will not be read, we should use something like:

FOR /L %A IN (0,0,1) DO ( DIR /S )

There are different ways to color all or part of the console: the color command (which can be refined by also setting a background color), just the prompt, highlighting text only by echoing ANSI characters, third-party utilities...

But if I want to change my Windows wallpaper, it's independent of such a DOS command, I must create or use a 24-bit bmp image and use, I haven't tested not in a batch but at the command line:

reg add "HKCU\Control Panel\Desktop" /v Wallpaper /d "C:\Path_to_image" /F RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True

The first command triggers nothing

The second one does not become .cmd with the gear wheel as the thumbnail icon!

Any command aimed at the registry executes silently (that's actually the danger).

I don't understand your second comment at all (even if I input an incorrect syntax in a cmd file, the batch won't execute, but it will remain a cmd file with its icon); there's no question of executing the two lines separately although maybe we can, they're in a Batch (new text file saved as toto.cmd).

It's worth noting that the image used must be a 24-bit bmp (and adapted to the screen resolution), which is one of the quirks of Windows since it will be immediately converted to jpg and stored in a designated location.

Not many people have bmps on hand, save a jpg as a 24-bit bmp using the graphic software of your choice.
