Alternative to sed regexp

[dxcSithLord]

Not a bug, but have you considered, for readability,

curl -sL "https://api.github.com/repos/wagoodman/dive/releases/latest" | \
     grep '"tag_name":' | \
     awk -F'"' '{print $(NF-1)}'

with awk instead of using sed? The awk statement uses quote (") as the field separator, making the version one less than the NF (number of fields)
Consider, also using "<RETURN>" to wrap the lines so they can be seen more easily. The "" must be followed by return and be the last character on the line (in case you did not know).

	DIVE_VERSION=$(curl -sL "https://api.github.com/repos/wagoodman/dive/releases/latest" | grep '"tag_name":' | sed -E 's/.*"v([^"]+)".*/\1/')
	curl -OL https://github.com/wagoodman/dive/releases/download/v${DIVE_VERSION}/dive_${DIVE_VERSION}_linux_amd64.deb
	sudo apt install ./dive_${DIVE_VERSION}_linux_amd64.deb
	```
	Using snap:
	```bash
	sudo snap install docker
	sudo snap install dive
	sudo snap connect dive:docker-executables docker:docker-executables
	sudo snap connect dive:docker-daemon docker:docker-daemon
	```
	**RHEL/Centos**
	```bash
	DIVE_VERSION=$(curl -sL "https://api.github.com/repos/wagoodman/dive/releases/latest" | grep '"tag_name":' | sed -E 's/.*"v([^"]+)".*/\1/')

Just a suggestion.
