Can't we already fire a git status instead of telling the user to do so?

[AkshDesai04]

Adding a call for git status ourselves would make it more functional.

if [[ -n $(git status -s) ]]; then
echo "Error: git directory is not clean; Running 'git status'"
git status
exit 1
fi

[TWiStErRob]

output the value to show which one?

Suggested change

	echo "Error: RELEASE_BRANCH env var is undefined or does not contain 'release_branch'"
	echo "Error: RELEASE_BRANCH env var (${RELEASE_BRANCH}) is undefined or does not contain 'release_branch'"

	echo "Error: git directory is not clean; check 'git status'"
	echo "Error: git directory is not clean; running 'git status'"
