How to get lessc Mac os x terminal compiler to work?

Question

macOS

On duty, I had to work with Bootstrap, which didn’t want to compile with SimpleLess, I had to put grunt node.js in the terminal
and run the command
lessc bootstrap.less > bootstrap-custom.css
and finally my document with custom variables was compiled, but here's the thing, how to make this command run when the document is saved?
it's not very convenient to go into the terminal every time, because the document is saved many times a minute, help me out, maybe with the help of automator?

For such things, there is grunt|gulp|etc, as an option, put autoless - https://github.com/jgonera/autoless
