Linux disk space usage analyzer

6 приложений для анализа жесткого диска в Linux

Командная строка

Если вы истинный линуксоид, самый легкий и быстрый способ – использовать команду «df» в командной строке. Просто напечатать:

в терминале, и он покажет вам загрузку жесткого диска в процентах

Как видно из представленного выше скриншота, способ может служить лишь в качестве быстрого просмотра доступного места на диске и определенно не является самым удобным для проведения анализа жесткого диска.

Baobab

Большинство линукс-дистрибутивов с Gnome(в частности Убунту), используют Baobab в качестве дефолтного приложения для просмотра диска.Это замечательное приложение, способное до последней папки разделить и проанализировать структуру хранения данных на жестком диске. Просто укажите папки необходимые для сканирования, и в результате получите круговую диаграмму, отражающую количество занимаемого места каждым файлом.

KDirStat и GdMap

Если вы использовали WinDirStat в Windows, то согласитесь, что это очень удобное приложение, позволяющее анализировать и оптимизировать ваше дисковое пространство. Однако мало людей знают, что WinDirStat это на самом деле клон KDirStat. KDirStat обладает той же функциональностью что и WinDirStat (или может быть наоборот), за исключением того, что он предназначен для использования в Linux. Несмотря на то, что KDirStat разрабатывался для KDE, он также совместим с любым оконным менеджером X11.

KDirStat отображает ваши папки/файлы в виде прямоугольников. Чем больше размер файла, тем больше прямоугольник. Это позволяет вам быстро просмотреть файловую систему, и легко определить какая папка/файл занимают много места на жестком диске.

Gd Map это эквивалент KDirStat для Gnome, кроме того что он не отображает древовидную структуру папок, и не позволяет очищать жесткий диск.

Filelight

Подобно Baobab, Filelight, создает интерактивную карту концентрических, сегментированных колец, помогающих визуализировать использование диска на вашем компьютере.Вы легко можете приблизить нужные папки, путем клика на соответствующем сегменте колец.

Philesight

Philesight это реализация Filelight в качестве веб-приложения, может быть запущена на удаленном сервере, не имеющим графического интерфейса. Philesight использует командную строку для генерации PNG-файлов в браузере и включает CGI-скрипты для навигации по файловой системе. Одна из ее особенностей, красочная радуга концентрических колец, что делает ее весьма приятной на вид.

xdiskusage

xdiskusage маленькая программка, отображающая файловую систему иерархически, слева направо, прямоугольными фигурами, с размерами, соответствующими размеру файлов. Если вы сканируете домашнюю папку, слева будет находится прямоугольник, отображающий полностью папку home, а справа все файлы, находящиеся внутри нее.
Вы легко можете приближать/удалять, нужные папки, по двойному щелчку на соответствующем прямоугольнике.

10 Useful du (Disk Usage) Commands to Find Disk Usage of Files and Directories

The Linux “du” (Disk Usage) is a standard Unix/Linux command, used to check the information of disk usage of files and directories on a machine.

The du command has many parameter options that can be used to get the results in many formats. The du command also displays the files and directory sizes in a recursive manner.

Check Disk Usage of Files and Folders In Linux

This article explains 10 useful “du” commands with their examples, which might help you to find out the sizes of files and directories in Linux. The information provided in this article is taken from the man pages of du command.

How to Find the Size of a Directory in Linux

1. To find out the disk usage summary of a /home/tecmint directory tree and each of its subdirectories. Enter the command as:

The output of the above command displays the number of disk blocks in the /home/tecmint directory along with its sub-directories.

How to Find the Directory Size in Human Readable Format

2. Using the “-h” option with the “du” command provides results in “Human Readable Format“. This means you can see sizes in Bytes, Kilobytes, Megabytes, Gigabytes, etc.

How to Find Total Size of a Directory in Linux

3. To get the summary of a grand total disk usage size of a directory uses the option “-s” as follows.

4. Using the “-a” flag with the “du” command displays the disk usage of all the files and directories.

5. Using the “-a” flag along with “-h” displays disk usage of all files and folders in a human-readable format. The below output is easier to understand as it shows the files in Kilobytes, Megabytes, etc.

6. Find out the disk usage of a directory tree with its subtree in Kilobyte blocks. Use the “-k” (displays size in 1024 bytes units).

7. To get the summary of disk usage of directory tree along with its subtrees in Megabytes (MB) only. Use the option “-mh” as follows. The “-m” flag counts the blocks in MB units and “-h” stands for human-readable format.

8. The “-c” flag provides a grand total usage disk space at the last line. If your directory is taken 674MB space, then the last last two lines of the output would be.

How to Exclude Files with du Command

9. The below command calculates and displays the disk usage of all files and directories, but excludes the files that match the given pattern. The below command excludes the “.txt” files while calculating the total size of a directory. So, this way you can exclude any file formats by using the flag “-–exclude“. See the output there is no txt files entry.

How to Find Directory Usage By Modification Time

10. Display the disk usage based on a modification of time, use the flag “–time” as shown below.

12 Useful “df” Commands to Check Disk Space in Linux

On the internet, you will find plenty of tools for checking disk space utilization in Linux. However, Linux has a strong built-in utility called ‘df‘.

The ‘df‘ command stands for “disk filesystem“, it is used to get a full summary of available and used disk space usage of the file system on the Linux system.

Using ‘ -h ‘ parameter with (df -h) will show the file system disk space statistics in “human-readable” format, means it gives the details in bytes, megabytes, and gigabyte.

Useful df Command Examples

This article explains a way to get the full information of Linux disk space usage with the help of the ‘df‘ command with their practical examples. So, you could better understand the usage of the df command in Linux.

1. Check File System Disk Space Usage

The “df” command displays the information of device name, total blocks, total disk space, used disk space, available disk space, and mount points on a file system.

2. Display Information of all File System Disk Space Usage

The same as above, but it also displays information of dummy file systems along with all the file system disk usage and their memory utilization.

3. Show Disk Space Usage in Human Readable Format

Have you noticed that the above commands display information in bytes, which is not readable at all because we are in a habit of reading the sizes in megabytes, gigabytes, etc. as it makes it very easy to understand and remember.

The df command provides an option to display sizes in Human Readable formats by using ‘-h’ (prints the results in human-readable format (e.g., 1K 2M 3G)).

4. Display Information of /home File System

To see the information of only device /home file systems in human-readable format use the following command.

5. Display Information of File System in Bytes

To display all file system information and usage in 1024-byte blocks, use the option ‘ -k ‘ (e.g. —block-size=1K ) as follows.

6. Display Information of File System in MB

To display information of all file system usage in MB (MegaByte) use the option ‘ -m ‘.

7. Display Information of File System in GB

To display information of all file system statistics in GB (Gigabyte) use the option as ‘df -h‘.

8. Display File System Inodes

Using ‘ -i ‘ switch will display the information of a number of used inodes and their percentage for the file system.

9. Display File System Type

If you notice all the above commands output, you will see there is no Linux file system type mentioned in the results. To check the file system type of your system use the option ‘ T ‘. It will display file system type along with other information.

10. Include Certain File System Type

If you want to display a certain file system type use the ‘ -t ‘ option. For example, the following command will only display the ext3 file system.

11. Exclude Certain File System Type

If you want to display a file system type that doesn’t belongs to the ext3 type use the option ‘ -x ‘. For example, the following command will only display other file systems types other than ext3.

12. Display Information of df Command.

Using ‘—help ‘ switch will display a list of available option that is used with df command.

7 of the Best Free Linux Disk Usage Analyzers

This article has been replaced by Essential Utilities: Reclaiming Disk Space

A disk usage analyzer is a utility which helps users to visualize the disk space being used by each folder and files on a hard disk or other storage media. This type of application often generates a graphical chart to help the visualization process.

Disk usage analyzers are popular with system administrators as one of their essential tools to prevent important directories and partitions from running out of space. Having a hard disk with insufficient free space can often have a detrimental effect on the system’s performance. It can even stop users from logging on to the system, or, in extreme circumstances, cause the system to hang.

However, disk usage analyzers are not just useful tools for system administrators. Whilst modern hard disks are terabytes in size, there are many folk who seem to forever run out of hard drive space. Often the culprit is a large video and/or audio collection, bloated software applications, or games. Sometimes the hard disk is also full of data that that users have no particular interest in. For example, left unchecked, log files and package archives can consume large chunks of hard disk space.

File systems can have millions of files. Keeping track of them can be an almost impossible task without some utility. Here steps in the disk usage analyzer. Linux has a good selection of this type of software for rooting out space eaters.

To provide an insight into the quality of software that is available, we have compiled a list of the 7 of the most useful disk usage analyzers. Hopefully, there will be something of interest here for anyone who wants to recapture their disk space.

Now, let’s explore the 7 disk usage analyzers at hand. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, screenshots, together with links to relevant resources and reviews.

Top 10 disk space analyzer tools to use on Linux systems in 2021

If you have limited storage space on your computer or you struggle for some space on your hard drive from time to time, it is always a good idea to keep removing unnecessary files from the hard drives to have more room for things that matter to you. But when it comes to analyzing the used and available space on a hard drive, you should choose some utility software that can help you observe and manage the files on your Hard Drive or any other storage in the simplest way. The good thing is, whatever operating system you are using, you will always find some utility programs that can help you to manage storage on your hard drive.

Talking about Linux, which is an open-source platform, you can also find several similar programs on Linux, and you can use one or many of them to manage the storage space on your hard drive or SSD. Even if you are not struggling for space on your storage device, it is always a grand idea to have such utility installed on your system, so that you can use it whenever you find that useful. So, today I will talk about the top 10 disk space analyzer tools that you can use on Linux.

Best Linux disk usage analyzer software 2021

Without any further delay, let’s get started with the list of free + opensource utility programs to analyze disk space on Linux distribution and have command over the storage space on your hard drive and SSD.

QDirStat

If you have ever used WinDirStat on your Windows computer, you will feel at home by using QDirStat. QDirStat is based on KDirStat, and WinDirStat is also based on the same. If you haven’t used WinDirStat on your Windows computer, let me give you a brief introduction to QDirStat. With the help of QDirStat, you can analyze the complete disk space on your Linux system, and the content will be displayed as square blocks. Depending upon how big a particular square block is, that actually reflects the actual size of the individual file on the hard drive, and as you have understood, the bigger the square, the bigger will be the size of the file and vice versa.

QDirStat Disk Analyzer for Linux

You can also click on any of the square blocks, which is very easy to observe, to find out what the file is and decide whether you should delete the file or not. That way, you can click on every big block to find out the actual file and make the decision to delete it. Depending upon the individual files, it might take some time to show you the name of the file, but that’s not significant. QDirStat also comes with additional features, which can make it easy for you to free up space on your computer’s storage. You can download it across many different Linux distributions which is yet another reason I will definitely recommend QDirStat.

Commands to install it on Ubuntu, Debian, and Linux Mint:

Disk Usage Analyzer for Linux

The next one in the list is Disk Usage Analyzer, aka. Baobab. It is also a great disk space analyzer tool, as the name goes, you can count on it. It comes by default in GNOME-based Linux distros, thus simply go to from Gnome menu Applications → Accessories and look for Disk Usage Analyzer.

Disk Usage Analyzer Full filesystem scan

Trust me it is one of the simplest tools that you can use on your Linux System to analyze disk space. Even though you cannot visualize the files on your storage device exactly the way as QDirStat in this program, you should choose this program if you are looking for an easy-to-use tool to analyze the available disk space on your storage device. The complete storage space on the hard drive or SSD will be displayed in the form of a pie chart which makes it easier for most users to manage the disk space.

As the user interface is very simple, it is many people’s favorite, and the software is capable enough to scan the full file system at once, or it can also track the individual folders chosen by you. The ball is in your court, and you can use the software exactly the way you want. You can also manage remote storage locations using FTP, SMB, HTTP, and other common protocols. Talking about the other advantages, you can also configure the software to always keep a tab on the changes made in the home directory, which can also save you some disk space at regular intervals.

Linux Ncurses Disk Usage- command-line tool

Next up is Ncurses Disk Usage, or ncdu, in short, is a powerful disk usage analyzer tool available for Linux, which comes with most features that most users will need from a decent disk space analyzer tool. The only problem with Ncurses Disk Usage is that it doesn’t come with a graphical user interface instead a text-based and for that, you might think it isn’t for you. But actually, it is not so, and considering the fact that a significant number of Linux users feel at home on the command line, Ncurses Disk Usage is much more powerful and feature-rich compared to most other command-line tools available for Linux.

Ncurses Disk Usage

After you launch the program in the command-line, Ncurses Disk Usage will start scanning your file system and you just have to follow the instructions given during startup to analyze the disk space like a pro. As it is a command-line tool, you can run it on computers, even with limited hardware resources, and the program interface can also be tweaked as per your requirement. Furthermore, you can also get a report of individual directories, and can also manage a web directory on a server using the widely known SSH protocol. If you are not a complete noob, when it comes to dealing with command lines, and have some minimum expertise to deal with the command-line, Ncurses Disk Usage will not disappoint you in any way.

JDiskReport Linux

As you might have got from the name, JDiskReport is a java-based program that you can use to effectively analyze the storage space on your hard drive or SSD, if you are using Linux. First things first, JDiskReport is a very easy-to-use utility software, and it comes with a very simple user interface that you will fall in love with. It has all the elements that most people will search for, in a disk analyzer tool. If you are familiar with Windows, on the left side you can find the complete directory structure and on the right side, you can find a pie chart that shows how much space is used by every single directory on your system.

You can also select the individual directories to find out the space consumed by those individual subdirectories and much more. Furthermore, you can also have a look at the top 50 files consuming the maximum space and can easily toggle between, whether you want to display the pie chart as per files or folders.

JDiskReport can easily find and give you the option to clean obsolete files from your system and, depending upon how you want to see the complete statistics, you can find the information in a tabular form, or get the same in the form of a pie chart. As it is a Java-based program, you can run without the software without any problems on any Linux distribution you are comfortable on.

Filelight KDE Linux

If you are not looking for a versatile solution to analyze disk space on Linux, Filelight is for you. What’s special in Filelight is that you can find the disk usage of your complete filesystem in a single pie chart, and visualization is done using a sunburst chart. The user interface is minimal and options are quite self-explanatory and there are no other additional options that might confuse you about how exactly it is going to work. By moving your mouse across the chart, you can also find additional details on the fly about the individual elements on the chart. There are always some files and directories on your system, which you will never want to delete.

Filelight KDE Linux

That said, you can exclude specific directories so that they are not displayed in the scans. The program is highly customizable, and you can change the user interface color based on your personal preference, and you can also see the content of every single file or directory by opening it in your default file explorer application or open the same in the terminal window. If you are willing to get some extra disk space and do not want to go to the steep learning curve of the other complicated disk analyzer tools, Filelight is the tool that you should start using right now. Not only for Linux, but it is also available on Windows 10 App store.

DUtree

Programmed using the RUST language, DUtree is one of the fastest disk space analyzer tools available for Linux. Just like most other disk space analyzer tools for Linux, DUtree will also show you the disk space usage using graphs and charts and the user interface is also very pleasing at the same time. The entire directory structure will be shown in the form of a tree so that you can easily understand what are the big files, which are consuming more space so that you can take the most appropriate steps to save some disk space.

Sometimes, several small files can consume a lot of space on your storage, and that’s where DUtree can also show you the total space consumed by small files, and additionally, you can also exclude certain directories from getting scanned. Long story short, it comes with all the necessary functionalities that you will ever need from a disk space analyzer tool available for any platform.

dutree, a tool to analyze file system usage written in Rust

The software is very simple to use, and the performance is spectacular. However, it will take some time for you to get used to this software and once you are ready you can have a wonderful grip over the file structure and storage space on your computer.

GdMap

Next up on the list is GdMap. It is yet another disk space analyzer tool for Linux but not updated for quite some time now, however, you can try out this tool which is similar to GdMap, but comes with an even simpler user interface that most users will find in handy. Just like GdMap, the files are displayed as square blocks, and the bigger the size or area of the square block, the bigger will be the size of the file and vice versa.

There are only a few options available, which makes it very concise, and is backed by a very easy-to-use user interface. Talking about the features of GdMap, it can run on all POSIX machines and the file contents are displayed in multiple colour gradients to make it easier for you to distinguish between multiple small files spaced together.

GdMap disk space analyzer tool for Linux

You can also edit the color as per your requirements and lastly, the thing that is what mentioning is that GdMap is very simple to use, and also comes in a very small package so that you do not need to delete any of your important files just to use this tool. There are also a few settings that you can configure to make the program exactly the way you want. If you are looking for a similar program like that of DUtree, just give GdMap a try and you will not be disappointed using this cool utility.

Unlike most other utility programs to analyze disk space usage for Linux, DUC is a versatile tool that can be used as a graphical program and also from the command line. Depending upon how exactly you want to visualize the file system or the storage space usage, DUC will represent it through different types of graphs as per your requirements. That’s what basically defines DUC. There are also a number of other key features available within DUC which makes it the best storage space usage analyzing app for Linux. If you are having huge chunks of storage, and most other programs are freezing for not being able to handle such large storage devices, DUC can work perfectly for you.

DUC, analyze the disk space usage for Linux

Furthermore, the user interface is also amicable, and the app comes in a small package, which makes it the favorite app for most people. The data is stored in an optimized database and if you are facing any kind of troubles using the program, you can always have a look at the documentation available on the official website, where you can find most information about the program and how to use it. There is also the online community, where you can get some assistance, lest you can’t find the solution to your problem in the documentation.

CrossDirStat

Compared to the most other disk space analyzing tools available for Linux, CrossDirStat is comparatively a new cross-platform tool, as the name goes, and it is yet one of the easiest tools that you can use to manage disk space on Linux. Talking about the user interface, which is the basic aspect in most utility programs, it features a material design like that of Android and you should feel at home just from that. Furthermore, in CrossDirStat, disk space usage is displayed in rectangles of different colors, and looking at the color schemes, you can easily understand which folder is consuming more space on your storage.

Obviously, you can also change the color scheme in the settings which eventually gives you more options for customization. One special ability of CrossDirStat is that you can also export the graphical representation of the disk usage to several formats, which include JSON, PNG, and other popular formats, and I believe in the coming days, there will be other formats to export the graphical representations.

CrossDirStat to analyze Linux disk usage

You can also select a particular directory and create a tree structure of the same to Export it to JSON. So there are a number of options that you can find in CrossDirStat, which makes it a versatile utility even after being new in its galaxy.

XDiskUsage

The last efficient disk space analyzing tool available for Linux, in this list, is XDiskUsage, and, even though it doesn’t have a great user interface, it can help you get the job done. The user interface might not be beautiful, but it is straightforward and can represent the directories on your storage in a tree-shaped structure, and each of the directories will be displayed as rectangles. Depending upon how much space a directory is consuming, and the number of files contained in it, the rectangles will look more cumbersome.

You can simply navigate between different rectangles and can also copy the path of the individual directories so that you can open them in your favorite file manager application or any other application depending upon your requirements. The installation of XDiskUsage is also very simple. You can just download the source code on your system, and compile it at that will eventually install XDiskUsage on your system so that you can use it. All the rectangles are white, and due to the absence of advanced features within the program, it is very lightweight, which makes it the go-to option if you want to remove unnecessary files, and want to keep a constant eye on the storage space of your system.

Storage space can really be a big problem when the size of the file size increases exponentially and you cannot upgrade the storage capacity of your system for any reason. Apart from the top 10 disk space analyzer tools available for Linux, which I have mentioned here, you can also find some other great programs that can do the same task on your Linux System. But the list of utility programs, which I have mentioned here to manage your disk space in Linux is more than what you will ever need. You will hardly need any other utility program in Linux to manage the storage space.

So, that was all about the top 10 disk space analyzing tools for Linux. Do you know any other great disk space analyzing tool that deserves its name in the list? Feel free to comment on the same below.
