Makefile For Loop on Windows
This is a similar question to the one I ask here. I am running on Windows XP.
I am trying to get for loop to work on Windows. Following the suggestion that I have to make su开发者_C百科re that the command are valid cmd command, I constructed a valid for loop batch command:
@echo off
FOR /F "tokens=4 delims=," %%G IN ("deposit,$4500,123.4,12-AUG-09") ^
DO ^
echo Date paid %%G ^
And put it in a Makefile. This is the content of the makefile:
all:
@echo off
FOR /F "tokens=4 delims=," %%G IN ("deposit,$4500,123.4,12-AUG-09") ^
DO ^
echo Date paid %%G ^
But still, I got an error:
FOR /F "tokens=4 delims=," %%G IN ("deposit,500,123.4,12-AUG-09") ^ make: *** [all] Error 255
Any idea how to fix this?
I've found the answer, this is the correct syntax that runs in Makefile Windows:
all:
@echo off
FOR /F "tokens=4 delims=," %%G IN ("deposit,$4500,123.4,12-AUG-09") \
DO \
echo Date paid %%G echo 123
I've found that by using && you can do multiple commands inside the for loop like so:
for %%i in ($(SOMETHING)) do echo %%i 1 && echo %%i 2 && echo %%i 3
This will printout something like:
1 1
2 2
3 3
your split is wrong, don't use ^. Do as following:
@echo off
FOR /F "tokens=4 delims=," %%G IN ("deposit,$4500,123.4,12-AUG-09") DO (
echo Date paid %%G
rem you can put as many lines as you want here, inside of braces
echo 123
)
Maybe you can call your batch command file from the Makefile?
all:
MyBatch.bat "deposit,$$4500,123.4,12-AUG-09"
With MyBatch.bat as follows.
@echo off
FOR /F "tokens=4 delims=," %%G IN ("%1") ^
DO ^
echo Date paid %%G ^
Beware the $ in the Makefile thought. $ is the escape characher and have to be doubled to get one real $ in strings.
