If there’s already a file named hello, running make hello will not run the recipe commands because Make found a file. To fix that, the target needs to be declared as phony.
hello:
@echo "Hello, Make!"
@echo "This recipe has two commands." > hello.txt
cat hello.txt$ make hello
make: 'hello' is up to date..PHONY tells Make that hello represents an action, not a file.
.PHONY: hello
hello:
@echo "Hello, Make!"
@echo "This recipe has two commands." > hello.txt
cat hello.txt$ make hello
Hello, Make!
cat hello.txt
This recipe has two commands.
