Inside a batch file on Windows I would like some variable to have the output of dir /b command.
How this can be achieved ?

Batch files didn't handle this use case very well. I did find one thread that describes a technique using temporary files.

On Windows, there's a better facility that comes pre-installed. Its called vbscript (and later there is Powershell ). Why don't you use vbscript instead.
strFolder="c:\test"
Set objFS = CreateObject( "Scripting.FileSystemObject" )
Set objFolder = objFS.GetFolder(strFolder)
s=""
For Each strFile In objFolder.Files
s=s & strFile & vbCrLf
Next
WScript.Echo s
The variable s now contains a list of files (equivalent to dir ). And if you want to store each filename into arrays, its also possible. (cmd.exe does not have arrays etc)

Just a note to whoever does not like this approach just because of not liking the VB syntax (such as myself) - the same utility (
wscript/cscript, which comes with Windows) supports JScript (the Javascript engine of IE) too. I've recently built an entire build system using JScript, and it was pretty good because I like Javascript.@ECHO OFF
setlocal enabledelayedexpansion
set LF=^
rem ** The two empty lines are NECESSARY
set output=
FOR /F %%i in ('dir /b') do SET output=!output!!LF!%%i
ECHO !output!
