Reviewing System Information for CentOS 7

[justindwalker87]

Hello, I'm in class and for our assignment we are to open the terminal and type hardinfo. I do so and "Command Not Found" comes up. IDK What the endgame is here but the next step is to click Summary, click Operating System, Processor, etc.... Anyone able to help me out?

Perhaps you misheard. It's not hardinfo, it's hwinfo.

I get command not found with that command as well, thank you

[TrevorH]

yum install hwinfo

(but you need to be root)

[justindwalker87]

how do you become root? i can't find an answer that works googling it? Thank you

[TrevorH]

If you did the install of the system then you know the root password and can use the `su -` command to become root. If you also checked the box during the install to set your own user up and make it an adminstrator then you can use sudo as you will be authorised to run anything using that. If someone else did the install and made you an administrator (a.k.a part of group wheel) then you will also be able to use sudo. If you don't have any of those then you need to ask your sysadmin to do it for you.

Here's what I got:

[justin@localhost ~]$ su - justin
Password:
Last Login: (date/time)
[justin@localhost ~]$ yum install hwinfo
Loaded plugins: fastestmirror, langpacks
You need to be root to perform this command

Running su - justin gets you to be the user "justin". Running su - or su - root gets you to be root.
