Current File : //home/silvzytp/dsr.silveroak.website/assets/vendors/bootstrap/build/lint-vars.sh
#!/usr/bin/env bash
#
# Approach:
# 1. Find variable declaration in the form of "$my-var: anyvalue"
# 2. Loop through found variables and find occurrences of each variable in all sass files
# 3. Filter out vars that occurred only once
#
# Run from command line with `build/lint-vars.sh scss`.
