In this video, I want to go over a quick couple of Linux commands, kind of get you familiar with Linux.
Now, Linux is a wonderful operating system and it does have some GUI based programs.
Meaning if I go to the menu here, I can go to one of these and I can click on one of these and I'll
open a program.
However, if I open most of these, it's going to open up in a terminal window, which is this window
here for windows users, it's basically a command prompt.
Um, Mac users will recognize as a terminal, and we can also open it by going down in here and clicking
this black box.
And it'll say terminal terminal emulator.
And I zoomed in on the terminal here.
If you want to do that yourself.
Hit shift control and the plus key twice and I'll zoom in a little bit.
The other important thing about Linux is Linux is case sensitive.
So if I try to go to a desktop desktop, it has a capital D.
If I do lowercase it's not going to recognize it.
So you do want to pay a very close attention to to things like that.
So a couple things, uh, Linux commands that you want to know is ls that will tell you what directory
you're currently in.
CD is for change directory.
Say I want to go to desktop.
I could do desktop.
And I'm going to intentionally put it all lowercase and show you what's going to happen.
So.
It's going to say no such file or directory.
That's because again, Linux is case sensitive.
So I could do CD space capital D.
And another great thing about Linux is it's uh, it has autocomplete.
So if, if I hit the tab key.
It all finished typing what it thinks I'm going to try to type in so I can do that.
And now I'm in the desktop, I can do LS to show me what's in there.
Okay.
I could do CLS to clear the screen.
Or rather clear.
Sorry.
And if I want to go back, I could do CD space dot, dot.
And that'll take me back directory.
I can do ls again and.
Takes us back.
It shows us everything again.
Another important command is sudo.
Now sudo is basically running things as administrator.
By default, Linux doesn't run things in administrator to give you more protection, so something bad
doesn't happen.
Malware doesn't try to take over your system as easily.
So if we want to run something as a minister, we type in sudo space and whatever the command is and
that's going to run it.
Now we're going to learn a lot of other stuff.
Um, other commands throughout the course.
We're going to be downloading things from GitHub and whatnot, and I'll be walking you through those
commands.
Also, other important commands you want to know are sudo apt get space update.
And that's going to update our operating system.
Likewise we could do sudo apt get.
Upgrade.
And that's going to look for if there's any upgrades to the operating system.
So we don't have to go out and try to look for those updates.
We can simply type those commands and update the operating system.
And these are really important to run periodically.
So those are some basic commands for Linux.
Again, as we go through the course and we start using other commands like um, um, GitHub downloading
for GitHub and whatnot and running specific Python commands while I walk you through that also.
But these are the very basics that you're going to want to learn.
Thank you for watching.
I'll see you next video.
