Answer 4

Q.4: What does `$` mean?

A.4: `$` is a separator. Everything before it is the computer generated prompt and everything after is the user typed command

Note on answer: Most example commands I show will start with `$` just as an indicator that the example command is ran in the shell.

مع ملاحظة: أنه إذا كان المؤشر$ فهذا يدل على أنك مستخدم عادي أي بدون امتيازات الجذر. أما إذا كنت تعمل بصلاحيات الجذر سيظهر لك علامة #.

Great note, thank you!

Tons and lessons elsewhere, and this is the first time I am hearing this. Thank you!

You are right thank you o here from you

Okay

mmmmm not really.

TL;DR

$ is a standard privilege user
# is root. No passwords or sudo needed.
The reason you often see a $ sign in an example is to show you which user you need to be in order for the script / command to work.
End TL:DR

Example 1: Q0h313th@pico-2019-shelll1:~$

The dollar sign in example 1 indicates you're running your commands as a standard user and need elevated permissions for certain commands. When you use sudo it is because you do not have root privileges. You use sudo to temporarily elevate your privileges and then enter the accounts password. if your account looked like:

Example 2: root@pico-2019-shelll1:~#

[notice the pound (often referred to as a hashtag in mainstream media now) verses the $ dollar sign] In example 2 you are now running as root. A command which previously needed sudo followed by your accounts password scan now be entered without sudo and it will run. This is obviously very dangerous, which is why the $ user and the need of sudo with a password following was set up.

thanks @Exzou was wondering the difference between the '$' and the '#' on my kali linux shell but is root just like admin privileges?

Yes @jmorgan28-01. You're right.

gracias por la explicación más detallada

That's all above comments it sounds like correct. But on my side I just reply that "$" as a shell prompt symbol.
