How can I do it? I know I can add another rule to accomplish that, e.g.
Why do you even need $(shell ...) here? All the commands in the recipe
are implicitly evaluated by the shell, so just do your conditional there:
outfile = out.txt
$(outfile):
@echo -n "STRT: $@ "; if [ -f $@ ]; then echo exist; else echo absent;
fi
@touch $@
@echo -n "DONE: $@ "; if [ -f $@ ]; then echo exist; else echo absent;
fi

Well Brian, the example presented by me is just a fabricated one, not
for my real world use. I use $(shell ) just to introduce a make variable
or a make function so that my question becomes concrete. My real world
case regarding this problem is quite a bit complex so I'd like not to
talk about to it directly.
