I (using windows) have implemented the code given here. For which when I do npm run winBuild where winBuild is "winBuild": "set \"GENERATE_SOURCEMAP=false\" && react-scripts build" I get the below image in my console 
and 
The post build I have is "postbuild": "purgecss --css build/static/css/*.css --content build/index.html build/static/js/*.js --output build/static/css && find /path/to/build/static -type f \\( -name \\*.js -o -name \\*.css \\) -exec gzip {} \\; -exec mv {}.gz {} \\;"
Taken from above link. But then I realise that it is asking for /path/to/build/static which will vary. How do I find path to static files in create-react-app and if this file name will vary how am I getting File sizes after gzip: as shown in image in my console?
In the Docker container in Linux machine, it's throwing an error as No such file or directory.
