Extjs 4.1 deploy application by minfied JS files - Sencha Cmd

[asifu9]

Hi All,

I want to deploy an application which is build using Extjs 4.1.
I followed below link to deploy but its not working.
http://docs.sencha.com/ext-js/4-1/#!/guide/getting_started-section-3

Then i came to know about Sencha Cmd, but i am not understanding how to deploy it by minified JS files.

Need help on how to deploy application by minifying JS files.

Thanks,
Asif
