How do I make SMPTE colour bars using batch

Question

I want to make this image

using Batch, but I'm not sure how- I know how to echo in batch, but I don't know what to echo, how to get the right colours and what the size of the windows should be. Should the size be:

mode con:cols=37 lines=22

@Dai I am making it into a virus- not a real one- one to prank someone and this will part of the special effects. Don't judge me. — , Jul 23 '17 at 11:37
On Windows 10 you could use [Ansi escape sequences](https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences) to create this picture — , Jul 23 '17 at 12:55
Alternatively, you can try `cecho.exe` which should work from WinXP and above. — , Jul 25 '17 at 02:23
@SteveFest I am not sure what you mean, as I get this message: 'cecho.exe' is not recognized as an internal or external command, operable program or batch file. So, I downloaded it from https://www.codeproject.com/Articles/17033/Add-Colors-to-Batch-Files and do I put it into the System32 folder? — , Jul 25 '17 at 08:41
@cybergodfather666 Note: On your victim's system, you will need `cecho.exe` in System32 folder/ or your batch file folder/ a folder in path variable. I recommend you to copy `cecho.exe` with your batch file to your victim's PC. — , Jul 25 '17 at 08:53
But please can you give me the code on what to put into my batch code? As I'm a beginner and I'm not sure what the mode would be and how to get the bars @SteveFest — , Jul 25 '17 at 08:53
First off: Do `cecho.exe /?` - It tells your everything. This command's ability is too much to be fit in the comment. — , Jul 25 '17 at 08:54
@SteveFest thats fine, but is the code to get it too much? If so, can you give it in blocks? — , Jul 25 '17 at 08:58
@cybergodfather666 I'm writing the actual code. My estimation: generating this picture + `mode` command would only take 30 ~ 50 lines. — , Jul 25 '17 at 08:59
@cybergodfather666 or if you use `for` loop, this could be shortened to ~10 - 20 lines — , Jul 25 '17 at 09:00
OK, thanks @SteveFest and please upload it when finished. Thank You! — , Jul 25 '17 at 09:00

Using cecho.exe can do what you need.

mode con:cols=70 lines=20
for /l %%G in (1,1,10) do (
     cecho.exe {07}aaaaaaaaa{#}{06}aaaaaaaaaa{#}{0B}aaaaaaaaaa{#}{0A}aaaaaaaaaaa{0D}aaaaaaaaaa{#}{04}aaaaaaaaaa{#}{01}aaaaaaaaa{#}{\n}
)

for /l %%G in (1,1,2) do (
     cecho.exe {01}aaaaaaaaa{#}          {0D}aaaaaaaaaa{#}           {0B}aaaaaaaaaa{#}          {07}aaaaaaaaa{#}{\n}
)

 for /l %%G in (1,1,3) do (
     cecho.exe {01}aaaaaaaaa{#}{0F}aaaaaaaaaa{#}{05}aaaaaaaaaa{#}                                        {\n}
)

You can change the a's to whatever character you like - just note the codepage issue. You may want to change codepage(chcp) to 65000/65001 for Unicode in UTF-7 and UTF-8. Codepage 437(OEM is also a good option)

mode command changes the console size
The first for /l loop runs the command in the brackets 10 times
The second for /l loop runs the command in the brackets 2 times
The third for /l loop runs the command in the brackets 3 times
cecho echoes out colored text.
- {nn} is the color code, followed by the text
- {#} resets to the original console color
- {\n} creates a new line
- When you want to cecho a {, make sure you write {{.

This is very helpful and useful @stevefest thanks! I have ticked it just so you know, and THANKS! — , Jul 25 '17 at 12:29
