How to make css prefixes using lessc command?

Question

css

I need to compile less into css with the lessc command - less is installed globally, the question is how to prefix styles through this command, now I use it like this:

lessc  .\test.less test.css --clean-css="--s1 --advanced --compatibility=ie8"

the command compiles less for me and minifies the css output with clean-css.
the question is how else to put prefixes in the same command? preferably with autoprefix package
thanks
