批处理Windows 7：循环读取文本文件

Question

I have a text file like that:

info1 subinfo1

info2 subinfo2

info3 subinfo3

I have to perform a loop on command using these infos. I do it like that:

for /F "tokens=1,2" %%a in (%cd%\%SCANS%) do (
        set stack=%%a
        set orientation=%%b 
        command1 -i test -o test -option1 %stack% -option2 %orientation%
)

It doesn't work. the option are always the same.

and Indeed if I do:

for /F "tokens=1,2" %%a in (%cd%\%SCANS%) do (
set stack=%%a
set orientation=%%b   
echo %%a
echo %%b
echo %stack%
echo %orientation%
)

I have this:

info1_lr

axial

info2_lr

sagittal

info3_lr

coronal

info2_lr

sagittal

info2_lr

sagittal

info2_lr

sagittal

Is that normal ?

Answer 2

so here is how I did:

    for /F "tokens=1,2" %%a in (%cd%\%SCANS%) do (
        setlocal enabledelayedexpansion
        set stack=%%a
        set orientation=%%b 
        echo %%a
        echo %%b
        echo !stack!
        echo !orientation!
        endlocal
)

after looking at delayed expression and it almost works for me.

except that I have a conflict with a way to "increment" a variable:

set cmdIntensityNLM=%cmdIntensityNLM% -i %RESULTS%/!stack!_blabla_%ITER%.nii.gz -o %RESULTS%/!stack!_blabla_%ITER%.nii.gz

I add to change it to:

set cmdIntensityNLM=!cmdIntensityNLM! -i %RESULTS%/!stack!_blabla_%ITER%.nii.gz -o %RESULTS%/!stack!_blabla_%ITER%.nii.gz
