Trying a VPS (hosting). I have installed Ubuntu 16.04 and created a user admin. Now I'm trying: ssh admin@185.149.129.42 The prompt becomes just a $.

I try: 

sudo su root

The prompt has become 

root@simple_project:/home/admin#

This line is in white letters.

I try: 

su admin

The prompt is in green letters:

admin@simple_project:~$

Well, in other words three cases:

  1. white $;
  2. white root;
  3. green admin.

I was somehow confused by case 1 for example. And I did:

su root

su admin

And I get my green letters up to the colon:

admin@simple_project:~$

This looks more familiar than just a bear $.

Could you tell me what these three cases mean? If they really mean anything.

  • $ means you have normal user privileges. # means you have root privilege. the third case indicates you are working as another user (admin) – ravery Jul 06 '17 at 06:09
  • the prompt ($PS1) is configurable - so you can make it anything you want. it's also varied by the SHELL you prefer (ie. % can appear instead of $ as default user prompt), which is again configurable (refer .bash_profile, .bashrc etc which can be in $HOME (your home directory) or if none there defaults are used from /etc etc maybe look at https://askubuntu.com/questions/404341/where-can-i-find-a-complete-reference-for-the-ps1-variable (I didn't look at much - first that showed up on a search) – guiverc Jul 06 '17 at 06:48

  • @ravery: Rude again. Take a chill pill, pal! Smile and be nice to others. Take care. – Lightness Races in Orbit Jul 07 '17 at 14:03
  • @LightnessRacesinOrbit -- not rude at all. I don't need you to post the same comment to every post I have made. – ravery Jul 07 '17 at 14:04
  • @ravery: Good thing I didn't then! And hopefully now you have learnt how to use this website it won't be necessary in the future, either. Cheers! (Yes, very rude.) – Lightness Races in Orbit Jul 07 '17 at 14:05
  • @LightnessRacesinOrbit - yoou would have if I didn't stop you. already 5 had been made – ravery Jul 07 '17 at 14:06
  • @ravery: That is simply false. You have not "stopped" anything. You have only been rude in the face of somebody trying to help you to become a more productive user. I shall now be ignoring you and your rudeness henceforth. – Lightness Races in Orbit Jul 07 '17 at 14:06
  • @LightnessRacesinOrbit -- I have not been rude. the rudeness is you repeatedly making the same post. not more to be said – ravery Jul 07 '17 at 14:08
