Given a command such as "docker-compose up", identifies the project root (the nearest ancestor containing e.g. "docker-compose.yml") and runs the command from there

proj.sh

#!/bin/sh

set -e

callee="$1"
invocation="$@"
target=""

case "$callee" in
	docker-compose)
		target=docker-compose.yml;;
	make)
		target=Makefile;;
	npm)
		target=package.json;;
esac

if [ -z "$target" ]; then
	echo "Unknown command"
	exit 1
fi

while [ ! -f "$target" ]; do
	if [[ $(pwd) = "/" ]]; then
		echo "No project file found"
		exit 1
	fi
	cd ..
done
echo "$(pwd): $invocation"
eval $invocation
