過去簡單式

quick back story, that Hang Man program from my first program, I ever coated video that was done in my CS through through three course, which was problem solving and programming one and to smash into a single course.

情態助動詞 A2

And alongside that course, I had to take CS 2 52 which was insured the UNIX for programmers.

未來簡單式

Today, we're going to take a look not as deep as we actually went in that class, but we're gonna take a look at the list of commands, some of the basic ones that we went over in that class.

I kind of want to see what I actually took over and to my actual career and which ones I haven't even seen since that class.

There's some commands that I use just about every single day.

There are other commands that I'll use on occasion.

Maybe when I'm looking something up or when I just really need to just, like, figure out a particular problem and, you know, use the terminal to fix that problem.

And then there's the really bottom of the bucket commands that I've personally never used since that we're going to go through that and kind of categorize some of these commands based on what was taught in that class.

CS 2 52 I haven't seen this page in, like, Well, besides yesterday when I was saying about making this video three years, four years, never take somewhere around there.

Sure, this curriculum is from, you know, 2018 but pretty sure all the content of this is the same as when I took it three or four years ago because not much changes with the UNIX.

I did take a look at a few of these try to find like a command list, and I did inside some basic UNIX commands and at all the way at the bottom of this.

It's funny about this is that you can take a look at this.

You're l, and you can take a look at all of this curriculum.

All you can't do is go into like the assignments and some of those specific things.

But you can take a look at all this curriculum for free.

A lot of the online courses from O to you.

The curriculum is online for free, just the assignments.

And you know, the teacher and all that stuff isn't available to you.

But basic UNIX commands all the way down commands a glossary.

Now this doesn't list all of the commands from what I remember, but it lists a lot of the basic ones and some of the difficult ones, but not any of the ones that really get into really deep detail because, you know, you could have some commands that are like three lines long for the sake of this video.

For the sake of my mind, we're not going to look at any of those.

So let's first look it while and directory manipulation CD that stands for Change directory.

I used that one the most out of anything because you kind of need to use that in order to change the directory mode.

I use this when particular, you know, private keys come into the equation where I need a file protection, as you can see right here.

But other than that, very rarely do I use this is generally kind of like a one and done type of deal for whatever site or credentials you're working with, CP never die you c p.

I just kind of normally do it the old fashioned way.

I'll have two files open a copy and paste whatever I need.

But generally, I don't need to copy an entire file in its entirety and just kind of need a little snippet from here.

There would have you and that kind of lays out our three categories I discussed earlier.

And this is one that I never use find I never used in all honesty when arrive Lennox that just essentially open up the file Explorer.

And then that's kind of how I find I make sure I'm in the proper directory so it could search down its branches, but I never use find in the actual terminal window.

From now on, I kind of forgot it existed at less.

That's one that you're gonna use all the time.

That is one Well, that lists the files in the directory.

So if you change to a particular directory.

You need to figure out what's inside that directory.

At last, I'm sure all the directories, all the files, what have you make dearer stands for making directory.

It'll create a new directory in your current directory.

I do use that one all the time, especially from trying to work on something and just make sure and then type in the directory name.

A fun little fact right here is that this little squiggly line doesn't matter what director you're in.

This squiggly line means home, though, as you can see right here.

If you do make sure told us last the name of your directory, then that will create a new directory inside your home directory.

The more you know, move her renames files.

I will use this when I am SS aged into a remote desktop.

Because a lot of times when I don't have access to a particular remote desktop, I will use envy to move particular files.

And a lot of times that I used to make dinner and stuff like that for, but I haven't used that since school.

I haven't used it, But in school, I'll need to S S H into my remote desktop that is owned by oh, to you.

And that's where this would really come in handy.

So I didn't actually have to load up the remote desktop.

Could just kind of, like SS agent and just kind of, you know, navigate around in the terminal.

No, don't use that RN for remove file, right?

I I do use that sometimes when I mess up the name or don't feel like anything, whatever Unmask says default permissions for newly created files.

And in all honesty, I was actually looking for this.

I forgot 100% what it was, but I wanted to compare two files and opened up moved.

The contents of each file that I listed actually may not be this one.

What I was trying to do was have a command.

I can't remember what the command was even till this day, and compare the text in two files.

I remember doing that, but I couldn't find the proper command to do that.

If you know that, can you please leave that in a common below?

Oh, Andy, Max, if you use a max, you're my sworn enemy.

I have plenty of other text editors that I would happily use before E.

Max, and you can open it the same exact way it's not living in the terminal, but you can open it using the terminal and open up sublime text or Adam or whatever text editor you like.

Heck, it could be no pad plus plus, if that's what you're into.

I know that one's going to get some dislikes on the video.

I feel like E max, and like them, I think them is somewhere down here Has you have them?

Not because it's better at least knows me, able to prove to me that it's better than you know existing text editors.

But because it's like either they're old school, and that's kind of what they've been using forever.

Or they're hipsters and they're like, I want to be like the old schools and that's what they use.

So let's make sure we like this video to counter act all the dislikes for me talking crap about them and e Max grab.

I use this a lot when I'm messing with my ports and all, honestly, not even 100% how I use it.

All I know is that when I'm messing with my ports, I use grip.

I do it So you don't use that along net stat as well whenever I mess it up.

I hate messing with the ports because a lot of times just really screws with me when I think something should work a particular way.
