how would i use a for loop in my makefile to redirect my output?

Question

run: $(CLASSES)
     for number in 2 4 6 8 10 12; do \
        $(JAVA) -cp $(BINDIR) Shuffled $$number ; \
     done

in this part of my makefile I run my class 6 times using a swap method of randomising, now my question is, would it be possible to redirect my output into a text file for each run and how would I go about doing this (can we use a for loop to redirect output for each run?)?

Answer 1

If you can edit the code of the Shuffled.java class, you can just... send all output to a file instead of system.out. Alternatively, just.. use a redirect:

$(JAVA) -cp $(BINDIR) Shuffled $$number >$$number.txt ; \

should produce files 2.txt, 6.txt, etcetera.
