Рассказываем, как запустить диспетчер задач в Linux.
Несмотря на более высокую отказоустойчивость Linux в сравнении с Windows, случается так, что нужно получить доступ к диспетчеру задач, чтобы «убить» какой-то процесс или просто отследить его поведение (избыточное потребление ресурсов или некорректную работу).
Открываем диспетчер задач в терминале
Отследить запущенные в Linux процессы можно с помощью текстовой утилиты htop. Она довольно наглядно отображает всю необходимую информацию. В ней есть удобный поиск конкретных процессов и взаимосвязи между запущенными программами. Также в программе можно посмотреть код PID процесса для его завершения через командную строку. В общем, это полноценный диспетчер задач, только jy работает в терминале и управляется не так, как мы привыкли в графической оболочке.
По умолчанию этого диспетчера задач нет в большинстве дистрибутивов. Поэтому придется скачать его. Благо он доступен в популярных репозиториях. Скорее всего, получится установить htop одной командой sudo название менеджера пакетов install htop.
Например, в Ubuntu (или в его дериватах типа Linux Mint и Elementary OS) — sudo apt-get install htop В Fedora — __sudo dnf install htop__
В openSUSE — sudo zypper install htop
Вот как будет выглядеть процесс установки на примере Linux Mint:
- Устанавливаем htop с помощью команды sudo apt-get install htop
Загружаем утилиту в систему с помощью стандартного менеджера пакетов
- Вводим пароль администратора для продолжения загрузки.
При вводе пароля набираемые символы могут не отображаться. Придется вписывать их вслепую
На этом все. Теперь остается разобраться с тем, как работает диспетчер задач. Элементы управления расположены в нижней части окна и закреплены за клавишами F1-F9.
Вот как выглядит наш диспетчер задач
Запускаем графический диспетчер задач
Если разбираться в терминале не очень хочется, то можно воспользоваться одним из доступных графических диспетчеров задач или загрузить какой-нибудь на свой вкус. Я рассмотрю диспетчер задач, встроенный в графическую оболочку XFCE, а также загружу аналогичную утилиту из рабочего стола Gnome.
Ищем системный вариант
Когда нет каких-то особых предпочтений в выборе программ, сначала стоит попробовать отыскать в системе уже имеющийся диспетчер задач.
- Открываем основное меню операционной системы.
В оболочке XFCE меню располагается в левом нижнем углу (как и в KDE). А в GNOME 3 оно отображается в верхнем левом углу
- Прописываем в поиск название программы (обычно она так и называется, «Диспетчер задач» или «Системный монитор»).
Ищем подходящее приложение
- Запускаем найденное приложение.
Вот наша утилита
И, собственно, все. В моем примере используется графическая оболочка XFCE со встроенным диспетчером задач. Диспетчер довольно минималистичен и не так функционален, как его аналоги. Но это дело вкуса.
Вот как выглядит диспетчер задач в XFCE
Загружаем системный монитор из графической оболочки Gnome
Большим спросом пользуется диспетчер задач из графической оболочки Gnome. Он относительно современный и отображает более подробную информацию о процессах, протекающих в системе. Тем, кто привык к работе с GUI, он точно понравится. Чтобы начать с ним работать:
- Просто скачиваем диспетчер задач с помощью команды sudo apt-get install gnome-system-monitor
Загружаем нужный компонент из базового репозитория
- А потом запускаем его командой gnome-system-monitor
Открываем диспетчер задач из терминала. При желании можно найти соответствующий ярлык в списке установленных программ
Интерфейс Gnome System Monitor делится на три части. В первой вкладке отображается список запущенных процессов, имя пользователя, который их запустил, и количество ресурсов, которое потребляют действующие программы.
Здесь можно управлять всеми запущенными программами. Есть удобный поиск по задачам
Вторая вкладка полностью посвящена отслеживанию потребляемых ресурсов. История нагрузки на процессор. История заполнения оперативной и физической памяти. А также история потребления трафика (загрузки и выгрузки).
Следим за используемыми ресурсами
В третьей вкладке отображаются все подключенные физические диски (включая внешние диски и флешки). Можно посмотреть сколько места занято и свободно.
Вот наши жесткие диски
Загрузка …

Transitioning to SysMonTask might just be the beginning of an exciting journey for Windows users exploring the expansive and vibrant world of Linux. And as they become familiar with its functionalities, it’s likely that SysMonTask will transform from a simple task manager into an integral part of their Linux toolkit.
Thanks to the desktop environments, almost all Linux distributions come with a task manager application. In addition to that, there are several other system monitoring applications for Linux that have additional features.
But recently I came across a task manager created for Linux that looks like … wait for it … the task manager of Windows.
You take a look at it and decide for yourself.
Personally, I am not sure if the likeness in the user interface is such a big deal but the developer and probably some other Linux users might disagree with me.
SysMonTask: A system monitor with the looks of Windows task manager
The open source software, SysMonTask, describes itself as a “Linux system monitor with the compactness and usefulness of windows task manager to allow higher control and monitoring”.
Coded in Python, SysMonTask boasts of the following features:
- System monitoring graphs.
- Shows stats for CPU, Memory, Disks, Network adapters, single Nvidia GPU.
- Support for listing mounted disks was added in recent version.
- User Processess tab can do process filtering, show recursive-CPU, recursive-Memery and aggregate values on coloumn headers.
- You can, of course, kill a process from the processes tab.
- Also supports system themes (dark and light).
Experience with SysMonTask
SysMonTask needs elevated privileges. You’ll be asked for your admin password when you launch it. I don’t like a task manager running with sudo all the time but that’s just my preference.
I played with a little to explore its features. The disk usage was pretty constant so I copied a 10 GB file from external SSD to my laptop’s disk a couple of times. You can see the spikes corresponding to the file transfer.
The process tab is also handy. It shows the accumulated resource utilization on the top of the columns.
The kill button is added at the bottom so all you have to do is to select a process and hit the ‘Killer’ button. It asks for your conformation before killing the process.
Installing SysMonTask on Linux distributions
For a simple application, it downloads 50 MB of archive files and takes around 200 MB on the disk. I think it is because of the Python dependencies.
At the moment of writing this article, SysMonTask is available for Ubuntu-based distributions via PPA.
On an Ubuntu-based distribution, open a terminal and use the following command to add the PPA repository:
sudo add-apt-repository ppa:camel-neeraj/sysmontaskYou’ll be asked to enter your password, of course. On newer versions, the repository list is automatically updated. So, you can install the application straightaway:
sudo apt install sysmontaskDebian-based distributions may also try to install it from the deb file. It can be found at the release page.
There is no ready-to-use package for other distributions. Whayt surprises me is that it is basically a Python application so a PIP installer could have been added for other distributions. Perhaps the developers will add it in the future version.
Since it is open source software, you can always get the source code.
Once installed, look for SysMonTask in the menu and start it from there.
Remove SysMonTask
If you want to remove it, use the following command:
sudo apt remove sysmontaskIt will be a good idea to delete the PPA as well:
sudo add-apt-repository -r ppa:camel-neeraj/sysmontaskYou may also use PPA Purge tool here which is a handy utility for dealing with PPA application removal.
Would you try it?
For me, the features are more important than the looks. SysMonTask does have the additional feature of monitoring disk performance and checking GPU stats which is something other system monitors usually do not include.
If you try and like it, perhaps you’ll like to add Ctrl+Alt+Del shortcut to launch SysMonTask to get the complete feel
