Terminal Lesson 3

[insecur]

Wait so if you reboot and hold cmd + s on boot it takes you to the command prompt as the root user. Because you get access to commands like reboot without using sudo.

[originalfunkman]

what's the difference between root and just being the admin?

[macheads101]

@originalfunkman In POSIX in general, only the root user has elevated privileges, and other users have no special privileges at all. Most systems now include the sudo command, which is where the concept of "admin" accounts comes in, because users in the admin group can run commands as root using sudo. So, if you are an admin, you can't do much more than a regular user without the user of sudo.

[NuntiusMusicae]

Am I supposed to be an admin in order to be able to use "sudo" command?

[macheads101]

@NuntiusMusicae Yes, you are

[macsimum76]

Can you disable GUI shutdown of your computer so you can only shut it down using the command line?

[drhesslen]

@Bigdaire good greif im 12 years old and i got it first time :P

[patrickvickery]

Hey

If i set my mac to reboot in 3 hours does terminal need to be left open for that time?

[freetrigger]

@scvuk1999 yes it is. while in terminal go to preferences on the toolbar or hit command comma and on i think its the second tab click homebrew and then hit default to change homebrew to default. :P

[scvuk1999]

Is it possible to change the colour settings on the Terminal to yours. Thanks from ur biggest fan

[supercooper92]

when changing another users password this way, what effect does does it have if they have filevault?

[MrLareneon]

Thanks you so much. This is just so helpfull

[TheTopSecretPerson]

How canI get the root password of my computer, I am not admin, but I can log into that session. Were can I change it and what does it correspond to?

[quinxx12]

Hey

So what is sudo exactly?? I mean what does it mean to be root?

[macheads101]

@quinxx12 Root gives you permissions that you do not get as a normal user. This includes being apple to change anyone's password, view anyone's files, change system settings, etc.

[joetommany]

@quinxx12 SUDO stands for Substitute User Do. Basically temporarily (5 minutes before you have to type sudo again) do something as another user. If you just type sudo -u username (replace username with the desired one) it lets you do an action as that user instead, without logging out of your current user's session. If you type sudo without a username it will assume you wish to perform that action as root. Root has all elevated privileges on a unix system, it will let you change anything.

[buildingmovies]

@Bigdaire It needs admin/root permissions to change it! it wants ur passwd because it needs permission!

y iz 1t bl3arry here 0n ur 0th3r v1d30s you have b3tt3r quiality

[malakov5]

My friend is admin on his computer and forgot his password to log in, will this sudo passwd "user" work? I recommended that he boot up in root and create a second admin, but if this works then it would be so much easier

[spawnofgravy]

No, I don't think this will work. Mac requires an admin password to use the sudo command.

[Babkockdood]

just type in your own password. terminal is just making sure you are who you say you are.

[macheads101]

type sudo before the command:

sudo passwd Guest

guest has a magic password to begin with.

[jj987987987]

is your account a root?

[ridthedelusional]

HI, do know all of these commands by heart, or do you have them written down?

[teluial]

I'm sure he knows them all. It seems odd because the Terminal isn't relevant to you, isn't personal, but to someone who's familiar with the Terminal it's just like knowing how to use the Dock and Spotlight and Finder. Do you have CMD+C and CMD+V memorized, or written down?

Everything you can do in Finder is a GUI analogue to something you can do from the Terminal. What Finder permits is a small subset of what you can do from the Terminal, as the shutdown example demonstrates.

[ridthedelusional]

yea that makes sense.

ya about every command memorized, they're so handy...

[MrLombreglia]

what do i do if i no longer know my admin password

[macheads101]

we have to videos, one is "How to enable 'root' on a mac" and the other is "make an admin account".

[MrLombreglia]

passwd: Unable to set extended node credentials for /Local/Default. Authentication failed.

It said this after i tried to change the password, what could i do now? I followed exactly what you said to do.

[macheads101]

Does your computer authenticate over a network? "e.g" a school computer.

[MrLombreglia]

im not sure what that means

[macheads101]

Do you use a networked account system? Is it YOUR computer or you schools or works. Were you there when it was being set up?

[MrLombreglia]

No it's my home compter

[macheads101]

did you do this

passwd

oldpassword

newpassword?

Try sudo passwd username

newpassword

confirmnewpassword

[MrLombreglia]

What can you do if you no longer have your old password, and only have one account. I'm stuck in my computer with no exits, i cant download anything.

[macheads101]

Power off isn't a command.

[labuhan7]

does the "sudo halt" shutdown the computer. if so what's the difference with

the "sudo shutdown -h now"

[macheads101]

There is no difference. Sudo halt does shutdown.

[labuhan7]

thanks, dude. great lessons.

[baileypetta]

yo dude i need your help when i type sudo passwd

is says password but it wont let me type any thang

[macheads101]

It won't display while you type a password, kind of like in other places you see the character as dots.

[Chremonwheels]

how do you get out of sudo after the command is done

[macheads101]

After you type that you are no longer in Sudo.

[freshasalwayz]

howd you change you text to those colors?

[freshasalwayz]

it sucks but im working with Tiger. i tried both of those and it didnt work

[macheads101]

Two Ways to do this in Leopard:

1. When you start terminal press Apple+Comma (Apple+,) and then click Settings witch should be one of the buttons at the top of the window. Then set settings for Basic.

2. When terminal is running hold control while clicking the Terminal Dock icon In the New Window menu click Homebrew. There are of coarse a bunch of other themes.

I will remind you that you can't do this on Tiger or Panther, Only leopard.
