I want to check if all the files that have a specific name have in them a string , if not to report them . I wrote this sequence and tried multiple some others, but I don't know how to access the contain of a file from list.
SOURCES := $(shell find $(SOURCEDIR) -name 'mod.mak')#here I take the list of targeted files (this works fine)
$(foreach File, Files,
$(if $(grep -q "aaabbb" "$File"),,@echo "WARNING Missing sequence")
)
