Empty output file

I'm having issues trying to get this to generate a minified output file. The mentioned output file is empty. I've tried these options. None work.

browserify -p tinyify src/main.js > foobar.min.js
browserify -p tinyify src/main.js -o foobar.min.js
browserify -p tinyify -o foobar.min.js src/main.js
browserify src/main.js -p tinyify -o foobar.min.js

And they all result in an empty foobar.min.js file. What am I doing wrong?
