In which directory npm 5 install ember

Basically I need to verify in Unix/Linux system that ember is installed through ant script after copying node_modules. What should be way to verify that, earlier version of npm install ember (node_modules/ember-cli/bin/ember), is still the same directory or there is any change ?

Ember now installs itself (at least the main core library) as ember-source. So in a modern ember-app the core ember version would appear in package.json as ember-source, and of course then you have ember-cli, ember-data and 15+ other default support libs. But yeah I think what you want is ember-source.
