A word of caution: this sort of goes against how make is intended to be used. But it can be convenient, and fun.

Example call:

  • $(MAKECMDGOALS) is the list of targets passed to make (action arg1 arg2)

  • $@ is an automatic variable expanding to the name of the target rul (action)

  • filter-out is a function that removes items from a list: filter-out $@,$(MAKECMDGOALS) -> arg1 arg2

  • % is a wildcard. If no rule is matched (as for arg1 and arg2 in the example), this goal will be run

  • : is a no-op. It means "do nothing", like the bash equivalent

  • @ in front of a recipe makes it silent

The result is that command will be invoked as: command arg1 arg2. make will still recognize arg1 and arg2 as targets, but will run the wildcard rule for them, silently doing nothing.

A side effect of the wildcard target is that make won't complain if we pass an invalid target - it will just silently do nothing:

And if one of the arguments we want to pass to command also is the name of another target, recipes in that rule will be executed as well - which probably is not somehting we want.
