How to use htop command

htop keyboard shortcut keys

The following commands are supported while in htop:

Command	Description
Up arrow key	Select (highlight) the previous process in the process list. Scroll the list if necessary.
Down arrow key	Select (highlight) the next process in the process list. Scroll the list if necessary.
Left arrow key	Scroll the process list left.
Right arrow key	Scroll the process list right.
PgUp, PgDn	Scroll the process list up or down one window.
Home	Scroll to the top of the process list and select the first process.
End	Scroll to the bottom of the process list and select the last process.
s	Trace process system calls: if strace(1) is installed, pressing this key will attach it to the currently selected process, presenting a live update of system calls issued by the process.
l	Display open files for a process: if lsof(1) is installed, pressing this key will display the list of file descriptors opened by the process.
u	Show only processes owned by a specified user.
M	Sort by memory usage (top compatibility key).
P	Sort by processor usage (top compatibility key).
T	Sort by time (top compatibility key).
F	“Follow” process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. This is useful for monitoring a process: this way, you can keep a process always visible on screen. When a movement key is used, “follow” loses effect.
K	Hide kernel threads: prevent the threads belonging the kernel to be displayed in the process list. (This is a toggle key.)
H	Hide user threads: on systems that represent them differently than ordinary processes (such as recent NPTL-based systems), this can hide threads from userspace processes in the process list. (This is a toggle key.)
p	Show full paths to running programs, where applicable. (This is a toggle key.)
Ctrl-L	Rfresh the screen.
F1	See this help menu.
h	Same as above.
?	Again, same as above.

Установка HTOP в RHEL, CentOS и Fedora Linux

Htop является интерактивным режимом реального времени и системой-мониторинга «процесс-зритель» который написанный для Linux. Он предназначен для замены программы top в Unix. Она показывает часто обновленный список процессов, запущенных на компьютере, как правило. В отличие от top, HTOP предоставляет полный список процессов, запущенных. Htop использует цвет и дает визуальную информацию о процессоре, своп и состояние памяти.

Сравнение между Htop и top

— В «Htop» вы можете прокручивать список по вертикали и горизонтали, чтобы увидеть все процессы и все командные строки.
— В «top» возможна задержка для каждого неназначенной нажатой клавиши (особенно раздражает, когда несколько ключей управляющие последовательности вызывают аварии).
— ‘HTOP’ стартует быстрее (‘top’, кажется, собирать данные в течение некоторого времени перед отображением).
— В «Htop» вам не нужно набирать номер процесса, чтобы убить процесс, в ‘top’ вы должны знать его.
— В «Htop» вам не нужно набирать номер процесса или значение приоритета для изменить приоритет процесса, в «top» вы делаете это.
— ‘HTOP «поддерживает работу мыши.
— ‘top’ старше, следовательно, больше привыкли к нему.

Установка HTOP на RHEL / CentOS 5.x/6.x/7.x, Fedora 12/13/14/15/16/17/18/19/20

На RHEL, CentOS, инструмент HTOP не доступен в репозитории yum по умолчанию. Таким образом, мы подключим репозиторий RPMForge.

Узнать какая разрядность ОС можно выполнив команду:

После включения хранилище RPMForge установить HTOP можно выполнив yum команду:

Установка Htop из исходного кода

Если вы предпочитаете устанавливать Htop от соусе, загрузить исходный код и скомпилировать его:

Как использовать Htop команду

После установки, просто введите HTOP в терминале, чтобы запустить его, и обратите внимание на большой текстовый режим график в верхней части дисплея:

Нажмите «F2», чтобы увидеть меню настройки HTOP :

Если вы хотите увидеть список процессов в виде древо процессов то используйте «F5» или «Т»

Измените выход интервала обновления

Чтобы изменить интервал обновления выхода Htop, используйте D-опции командной строки. «htop -d x». Где х упоминается в thenths секунд.

Htop – An Interactive Process Viewer for Linux

This article is the continuation of our Linux system monitoring series, today we’re talking about the most popular monitoring tool called htop, which is just reached version 3.0.5 and comes with some cool new features.

Htop Linux Process Monitoring Tool

Htop is an interactive real-time process monitoring application for Linux/Unix-like systems and also a handy alternative to top command, which is a default process monitoring tool that comes pre-installed on all Linux operating systems.

Htop has numerous other user-friendly features, which are not available under the top command and they are:

• In htop, you can scroll vertically to view the full process list and scroll horizontally to view the full command lines.
• It starts very quickly as compared to the top because it doesn’t wait to fetch data during startup.
• In htop, you can kill more than one process at once without inserting their PIDs.
• In htop, you no longer needed to enter the process number or priority value to re-nice a process.
• Press “e” to print the set of environment variables for a process.
• Use the mouse to select list items.

Install Htop in Linux

The htop packages are mostly available in all modern Linux distributions and can be installed using the default package manager from your system.
