je priklad na inkrementaci v Makefile , presmerovani stdin/stdout <> na
soubor counter snad uz win zvladnou :

   #
   # Increment counter and write buildnum.c
   # Do not name this rule buildnum.c although it creates buildnum.c
   # TODO: Add file locking for concurrent builds
   #
   buildnum: counter
         read LASTNUM < counter;         \
         NEWNUM=$$(($$LASTNUM + 1));             \
         echo "const int buildnum = $$NEWNUM;" > buildnum.c; \
         echo "$$NEWNUM" > counter

   buildnum.c: buildnum
   .PHONY: buildnum
   clean::
         -rm -f buildnum.c
