Hi, everyone.
In this lecture, we are going to learn one more very important Carmin, and that is getting help.
OK, so nearly every command and application or we can see utility has a dedicated health file in Linux
so that simply provide the guidance for how to use it.
So, for instance, if I needed help using the best wireless tool like aircraft Ginji so I could simply
type aircraft air crack Oxfordians.
Correct, engy and if I want help.
So what I need to do here is simply use double hyphen with the word help, OK, with the word help.
So after hitting enter, as you can see that this is the description.
When you scroll it up, is the basic description you'll find here after typing this particular command,
which is aircraft double hyphen help.
So what is the significance of using Doval hyphen and oxidised so.
Let me clear it first.
OK, I suppose that this is the two e-mail and I want to use like I, I just want to use with a simple
with a single hyphen ahead.
So what?
What we have here is in the convention and clinics, it is to use a double test before word option and.
We can use single dads with a single letter option, so I'm getting it, if not, so let me explain
it.
Suppose that they are using this as we all know that help is a word.
So what we need to use here is as for the convention of Linux, we need to use double hyphen.
OK, now suppose that if you're using only a single word, which is a hell of a stretch, so.
As for the convention, you need to use only a single hyphen, is this clear, guys, you can use double
hyphen help in case of what we need to use double hyphen.
You should use single hyphen in case of a single word.
Is this clear?
No, that's so.
When you enter the enter, simply come on, you should Chiuso description, like, let me do it again.
You can see the short description of the tool and guidance on how to use it, so in some cases you can
use simply again, let me clear it so you can use hyphen edge or you can also use hyphen questionmark
for getting help.
OK, suppose that I want to check the description to how to use and map.
So what I can do now let's try with Hyphen Edge now 10 Bazoft.
Any data, as you can see that I'm having does description to how to use and map.
OK, so now let's try with our older one which is OK and map the hyphen help and hit enter.
So I'm getting the same result.
Now let's try with our new one which is and map hyphen this.
Now this is not working here.
So unfortunately all the many applications supports all three options, like there's.
These all are the three options with the help of the you can see the help description of any particular
tool, but there is no guarantee the application you are using will or not.
So if one option doesn't work, then simply right next to one or another one.
So in this particular case, in case of Inmet, these two are working, but this is not working.
So this is how you can play with all of these.
OK, so this is how you can get help from from the files that are present that is present inside any
particular tool using Discman command, which is hyphen, hyphen, help, hyphen, edge, hyphen, questionmark.
OK, so this is all for this lecture from the next election or if you're going to see some very advanced
of against intermediate commands we can use inside the Leanness operating system.
So thank you for watching this lecture, guys.
