Tips to have separated linux terminal environments

on Terminal, Shell Script, Separated Terminal Environments

I am used to get headaches to find out a solution to have additional terminal that has independent environment with the main one. I searched via Google, nothing useful (because of my bad searching skill? I don't think so). I also tried iTerm and original OSX terminal together, pray for the magic appears, but it didn't not appear, of course, because they use same user bash. This action is just a hopeless action to prevent pulling my hair :D

So, why I crazily need this? Using multiple Heroku and AWS accounts with CLI pushed me to this situation. Imagine that I need to do heroku login and fill username, password or aws configure and fill keys (thanks for AWS CLI profile to resolve this but I still don't feel comfortable with it). This is really annoying when repeat them many times each day. Of course, I can write a bash file to do it more quickly but the separated terminal environment is still better :)

After some crazy hours, I realized that I made things complex myself, the solution is very simple (I think this is why I cannot find solution by searching, LOL): use 2 users, so easy. Just create additional user (namtv2), sudo su namtv2 and login second AWS, Heroku accounts, it works like a charm.

To create new user

  1. OSX
    If you are crazy fan of using terminal or you are anti-fan of using GUI, you can play with dscl to create user with nearly ten of commands

I will not use above option because using GUI is much easier. Open Users & Groups preference and you will know how to create new user
2. Ubuntu (other Linux distribution should be similar)
Ubuntu GUI to create user is not easier as terminal:
sudo adduser namtv2 and fill some information, it's all

Just a quick note to help others with same problem can find out solution quickly and prevent hopeless actions :)
