.PHONY
target
By default, Makefile targets are "file targets" - they are used to build files from other files. Make assumes its target is a file. These special targets are called phony and you can explicitly tell Make they're not associated with files. We don't need to use .PHONY
as long as you don't have a file with the same name as the task. The task will always be executed anyway, and the Makefile will be more readable.
echo "echo \"This is clean file\"" > clean echo "echo \"This is clean_runfile file\"" > clean_runfile cat > Makefile <<EOF .PHONY: clean clean: cat ./clean clean_runfile: cat ./clean_runfile EOF
Running the example:
make clean # executes the commands explicitly as it has .PHONY target cat ./clean echo "This is clean file" make clean_runfile make: 'clean_runfile' is up to date. piotr@Sylwia-zonka:~/src/myprojects/Makfile_adventures$
