Hello Friends Welcome back.
Welcome to this Manitobans section in this whole section we're going to talk about the disk management
utilities.
OK.
So in this lesson we're going to talk about how could this be serious.
OK we're going to learn how to do this.
This just in this lesson.
So there are two commands that is defined you which we can use to see that this is available on your
system to get selected practically.
Goodness.
So to take that this you just just type D.S. and I don't know.
It reduces this information in this format.
OK.
So let's see it one by one.
OK the first column was the information about the storage devices.
And this column is named as file system.
So here you can see there is the one it is a storage device.
OK.
There are different stores locations here in say we can see here these storage devices are the storage
locations.
And after that the next column shows us the total amount of memory available for as one you can see
here for eight to nine good to get is the total amount of space available.
And it is in kilobytes and the next column shows us the use of the memory out of this total available
memory that is 5 9 5 2 5 month memory used.
And the next column shows us the available memory out of this total available memory.
OK.
So 3 9 8 4 3 it is the available memory.
I'll go for it to 9 2 to.
And the next column shows us the memory in percentage of memory users percentage.
So here you can see 13 percent of memory is used by the out of total available memory and the last column
shows us the mumping location where these devices are mounted in Linux operating system every device
you connect is to recognize it as a file.
And if you want to access that device you need to mount that somewhere.
OK.
So in our upcoming lessons we can learn about it in detail how to mount the device.
Suppose you have a pen drive and if you want to see the contents you need to mount it.
So these are the mounting locations of various devices.
So in this way we could understand these things but there is one problem of when we see these memory
users or memory Well we can't understand what exactly you want to see.
So if you want to understand this in human readable form disprove it is switch edge.
Now here you can see it shows the information in Megabytes as dear one is currently having four hundred
seventy megabyte of memory and of that only 59 megabytes is used Dantley 90 megabytes.
Memories are variable.
In this way you can understand exactly what's going on and improve and switch and how many people I
find a.
Then it uses the information about the dummy file systems.
Ok the same information but including the dummy file system and their users.
And if you want to understand this woman it will form just image.
OK.
And then it gives the information in this format.
Suppose you want to understand or you want to see that this uses of a particular directory.
OK so suppose I want to see the best uses for this and there is the one then you can put a word like
this.
Find chanty and then the device location.
We know it gives us information about that particular directory or the particular device.
OK so in this way we can use the day of.
Come on.
OK.
There are some switches if you want to see the information in Megabytes destroyed them if you want to
see in kilobytes then proceed.
OK.
This way this tool uses this information in such detail.
And if you want to see the information based on I know numbers.
OK.
So just floored the switch here hyphen I know this gives the whole information OK according to diner
numbers.
That is the file system.
OK here you can see the columns that this file system.
Then the next column is I notice that is total line and then use it I nodes.
Then out of that the free and then the percentage of that is the percentage and then the Mountain Dew
says or more locations.
OK so in this way understand or we can get this information with this come on.
OK.
So the next command is do you do you use to get information about directly or directly based on information.
OK so suppose if you want to get the information for directly there then just provide the OR suppose
been been directed then just to come on like this do you.
And then and here you can see it gives you the information in this vein what you can't understand what
exactly that number is.
So understand that just proved the option like hyphenates.
And when you pro-white have Canet it gives the amount of space used by that directly been that is 15
megabytes.
If you want to see the grand total users of a directory they're just wild.
SH OK.
OK here I want to see.
Does your four root directory then hit into space.
Permission denied.
All good this.
OK.
It gives us the same information.
OK.
And if you want to see the information about all the files inside the directory.
OK.
Then just prewired the you and me and the directory name like this gives you the information about each
file and each space uses what you can't understand what these numbers are.
So just coordinates.
Now it will use that information whether it is in kilobytes or in megabytes.
OK so in this way you can use these commands to understand the disk space uses this.
