For loop: split string and echo every token

[mellimik]

Hey, I've been wondering can I define variable that contains words separated with spaces, then use FOR to go through the string and echo every token?

@echo off

REM DEFINE THE HOSTS THAT SHOULD BE SKIPPED (SEPARATE WITH SPACE)
set DISCARD=DC1 DC2 MGW

FOR /F "delims= " %%a IN ('@echo %DISCARD%') DO @(

	echo DISCARDED : %%a
)

but this only echoes the word before the first space.

C:\>skip.cmd
DISCARDED : DC1

C:\>

I know that I could use a text file containing all the words separated with new lines, but for the sake of simplicity I want to define everything inside one variable. I understand that using the "tokens=" parameter I can capture the amount I want from the line, but I just want to echo every token from the line and do something with them.

This is what I would like the output to be:

C:\>skip.cmd
DISCARDED : DC1
DISCARDED : DC2
DISCARDED : MGW

C:\>

Is this possible?

Cmd Promt is not my best langauge, but to do what you want would be simple in VBS script.

Save As Demo.vbs

Dim D1, D2, DISCARD 
 DISCARD = Array("DC1", "DC2", "MGW")
  For Each D1 In DISCARD 
   D2 = D2 & "DISCARDED : " & D1 & vbCrLf 
  Next 
 MsgBox D2,4128,"Finish"

@ECHO OFF&SETLOCAL
:: DEFINE THE HOSTS THAT SHOULD BE SKIPPED (SEPARATE WITH SPACE)
SET DISCARD=DC1 DC2 MGW
FOR %%a IN (%DISCARD%) DO ECHO/DISCARDED : %%a
PING -n 6 127.0.0.1>NUL

@ECHO OFF&SETLOCAL
:: DEFINE THE HOSTS THAT SHOULD BE SKIPPED (SEPARATE WITH SPACE)
SET DISCARD=DC1 DC2 MGW
FOR %%a IN (%DISCARD%) DO ECHO/DISCARDED : %%a

Exactly what I was looking for. Thank you! I just don't get what is the difference between FOR %%a IN (%DISCARD%) and FOR %%a IN ('echo %DISCARD%')

Th difference is

FOR %%a IN (echo %DISCARD%)

echo is a print command, so basically you are asking it to break down something being printed (how do you break down a command???) e.g. for <every part> of (print <variable>) is what you instructed it to do

FOR %%a IN (%DISCARD%)

break down the variable it its commpoent parts

e.g. for <every part> of (<variable>) is what you instructed it to do
