Let's take Makefile: alzu:; echo $@ Blibco:; echo $@ Norfowitz; echo $@ nillsburg; echo $@
Well let's say we want to run all the capital letter items. We could use $ make Blibco Norfowitz but that isn't as smart as $ make --all-targets-matching-regexp '^[A-Z].*' #Or instead these kinds or regexps: $ make --all-targets-matching-regexp '[A-Z]*' GNU Make 4.3
