Output the results of two commands in parallel

[Blitz]

I hope this trick can help anyone

1.bat

Code: Select all

@echo off
for /l %%a in  (1,1,10) do echo=%%a

2.bat

Code: Select all

@echo off
for /l %%a in (1,1,15) do echo=%%a

Parallel.bat

Code: Select all

@echo off
(for /f "delims=" %%a in ('1') do @echo=%%a&ping 127.1 -n 1 >nul)|cmd /v /c "(for /f "delims=" %%b in ('2') do @(set/pa=&&echo=!a!		%%b||echo=		%%b))&&for /l %%c in (,,,) do @set /pa=&&echo=!a!||exit /b"
pause

If you say that 1.bat and 2.bat are executed in parallel, then you are wrong. The FOR/F command first run the command and then, after the command had finishef, output the results. 1.bat and 2.bat never run in parallel in this way...

Yes, I know, I mean their output can be side by side and there is no need for temporary files or setting variables

I'm not even sure if this works reliably. Looks rather like some kind of UB. What happens if you decelerate one of the output loops? E.g. in 2.bat

Code: Select all

@echo off
for /l %%a in (1,1,15) do ping 127.1 -n 2 >nul&echo=%%a

Hi
Perhaps you mean that you want to make something like this code : Multi-Threaded_Network_IP_Ports_Scanner.bat
