What would you like to do?
Script finds all SCSS variables (e.g. $some_variable-NAME1) which are used in code only once (e.g. declaration or using variable from some framework). Tested on MAC and Linux.
#!/usr/bin/env bash
# HOW TO USE
# Save code to file
# Run as "SCRIPT_FILE_NAME SASS_DIRECTORY"
# e.g "./find_unused_variables.sh ./sass"
VAR_NAME_CHARS='A-Za-z0-9_-'
find "$1" -type f -name "*.scss" -exec grep -o "\$[$VAR_NAME_CHARS]*" {} ';' | sort | uniq -u
