sass-cli

I don't want to install Ruby, but I want to compile *.scss from the command line.

Same here.

If you use the Ruby CLI, you will find some things missing. This command accepts two arguments, which may either be a pair of filenames or a pair of directory names.

Examples

Two files:

$ sass assets/scss/file.scss build/output.css

Two dirs:

$ sass assets/scss build/css
