How to empty and refresh Bitnami in MacOS in terminal shell?

I found a safe way to start Bitnami like a clean copy, without remove your old copy.

Make sure you close and exit your Bitnami App in MacOS.

First change to the directory of Bitnami.

Justins-MacBook-Pro:~ juzhax$ cd ~/.bitnami/

Justins-MacBook-Pro:.bitnami juzhax$ ls -la
total 32
drwxr-xr-x    6 juzhax  staff   192 Mar 21 20:09 .
drwxr-xr-x@ 123 juzhax  staff  3936 Apr 16 19:57 ..
-rw-r--r--@   1 juzhax  staff  6148 Apr 27 11:49 .DS_Store
-rw-r--r--@   1 juzhax  staff  1489 Mar 20 21:10 metadata-bit.json
-rw-r--r--@   1 juzhax  staff  1482 Mar 21 20:08 metadata.json
drwxr-xr-x    5 juzhax  staff   160 Nov 11 02:50 stackman

Justins-MacBook-Pro:.bitnami juzhax$ mv stackman stackman.bak

Then you start your Bitnami App again, it will generate a fresh copy for you.
