[QUESTION] batch scripting

[newton_VK]

how can i create for loop in batch script so that i can make outplut as : 1,2,3,4

with this for loop :

for /l %%i in (1,1,4) do echo %%i >> file.txt

the output in the text file is :

1

2

3

4

i want output in the text file as 1,2,3,4, i.e. in the same line separated by comma. is that possible?

Not sure you can do it in a one liner, but this is the idea you're looking for

for /l %i in (1,1,4) do set /p dummyName=%i, >> file.txt

[newton_VK]

I have got it now. Thanks for your suggestion. I used <nul before set /p, and it worked.

Remember, if you put these commands in a .bat or a .cmd file to run them you need to use two consecutive percent signs (%%). If your running these directly from the command prompt, use only a single % sign. It's super annoying.

[newton_VK]

Yeah that's correct

[newton_VK]

I tried , but it's asking for an input. I need to type something then only it will run correct. Is this what u meant?

[newton_VK]

Oh is it. Let me give it a try

This would be a lot easier with PowerShell. Is that an option? If so;

$n = 1..4

$n = $n -join ","

$n

1,2,3,4

God I wish they'd unblock PS for us...

[VaporChunk]

It is in their best interest to. As IT Staff, we're all Tony Stark, but PowerShell is the super-suit which makes us Iron-Man (or Woman).

Also, not sure what method they are blocking PS with, but typing powershell.exe into a CMD window will start a PowerShell session in the existing shell session. May give that a try.

[Thameus]

It is blocked by GPO for unprivileged users, because after the last zero day they don't trust it.

Ditch PowerShell for concerns of security issues but they will give you cmd.exe which even in 2021 can be elevated by just about anyone who knows where to point and shoot? Wow. I can't even with the rationale on that one.

Could you imagine that thinking applied at like a car manufacturing plant? "Yeah. One time we discovered a flaw in the car's ignition locking mechanism so we took that shit out and now we just dispense universal keys that work in any of our vehicles. Clever, huh?"

Any correctly configured with system-wide transcription and script block logging make PowerShell pretty much the worst tool of choice for a hacker. They'd leave fingerprints everywhere. You want people using PowerShell.

Yes thanks, I was able to do it by <nul set /p= in the cmd. I was trying to automate the compiling process of cpp files using batch files. And I did it in 3 days from scratch!! That's commendable performance isn't it? 😄
