| 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. |
Suppose
mmmmm not really.
TL;DR
$is a standard privilege user#is root. No passwords orsudoneeded. The reason you often see a$sign in an example is to show you which user you need to be in order for the script / command to work. End TL:DRExample 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
sudoit is because you do not have root privileges. You usesudoto 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
sudofollowed by your accounts password scan now be entered withoutsudoand it will run. This is obviously very dangerous, which is why the $ user and the need ofsudowith a password following was set up.A more accurate and concise answer can be found here:

That's all above comments it sounds like correct. But on my side I just reply that "$" as a shell prompt symbol.
$
@Exzou it was very insightful!.
'$' a dollar sign is a convection to a prompt to show that a shell is ready to take command, but it vary for root user ( # is used in a prompt) and for regular user '$ ' is used but both are prompt sign indicating shell is ready for input
interesting
Well, I use a ZSH, it shows an arrow
Yes @jmorgan28-01. You're right.
