# Running make in a set of subdirectories

```
.
├── Makefile
├── scripts
│   └── Makefile
└── tasks
    └── Makefile
```

All Makefiles have `all`, `test` and `lint` targets.

```
SUBDIRS = scripts tekton
TOPTARGETS = all lint test

$(TOPTARGETS): $(SUBDIRS)

$(SUBDIRS):
  $(MAKE) -C $@ $(MAKECMDGOALS)

.PHONY: $(SUBDIRS) $(TOPTARGETS)
```

`$@` is an automatic variable that contains the target name (one of `SUBDIRS` in this case).
