Today I learned that you can use Makefiles to create simple task-runners.
Stuart Feldman invented Make in 1976 to automate build processes for C programs. But you can use it for other languages, too.
For example, Vladislav Supalov uses this
Makefile for Docker commands:
all: @echo "Usage: build or run" build: docker build -t test . run: docker run --rm -it test
Now run the file with your terminal:
make > Usage: build or run
Build the Docker container via
make build or run the container via
Pitfall: Tabs vs Spaces⌗
My editor replaces tabs with spaces.
Makefiles need tabs, otherwise you’ll get an error:
Makefile:5: *** missing separator. Stop.
If you use Vim, you can
setlocal noexpandtab to revert spaces to tabs.
