Is it possible to pipe an output to a for loop?

Hi guys, new here.
For example, I have this here:
dir >dir.txt
for /f "tokens=5" %%a in (dir.txt) do @echo %%a
...but I'd like to do this if I can:
dir | for /f "tokens=5" %%a in (output of dir) do @echo %%a
Thanks for your help.

You can process a command into a for loop. Use apostrophes into the brackets.
Code: Select all
for /f "delims=" %%a in ('dir /b') do echo %%a
Option /b means that only the filenames are outputed, no header.

Ahh, thanks again. I'm very rusty.

echo off
set a1=1
set b1=2
set c1=1
for %%x in (%a1%,%b1%,%c1%) do echo %%x > pippo.txt| set /a x=%%x+1

rem example pipe
echo off
:10
set /a a1=%random:~1,1%
set /a b1=%random:~1,1%
set /a c1=%random:~1,1%
set /a d1=%random:~1,1%
for %%x in (%a1%,%b1%,%c1%,%d1%) do for %%y in (%a1%,%b1%,%c1%,%d1%) do echo %%z > pippo.txt| set /a z=%%x*%%y
goto 10
