Htop [non-internal command] an interactive process viewer that can dynamically observe the process status of the system

Add that the htop command is an interactive process viewer in the Linux system, a text-mode application (in the console or X terminal) that requires ncurses.

Compared with the traditional top of Linux, htop is more humanized. It allows users to operate interactively, supports color themes, scrolls through the list of processes horizontally or vertically, and supports mouse operation.

Compared with top, htop has the following advantages:

You can scroll through the list of processes horizontally or vertically to see all the processes and the complete command line.

Faster than top on startup.

You do not need to enter a process number when killing a process.

Htop supports mouse operation.

Compared with the two, top is more tedious.

Disadvantages of top:

Only keyboard operations are supported.

The display is monotonous.

The command can be applied to multiple processes, such as "kill". It will be applied to all marked processes ````shell # Htop. Click Setup or press F2 to enter the page # 1. Meters sets the display information at the top, which is divided into left and right sides. Left column represents the information displayed on the left, and Right column represents the information displayed on the right. If you want to add a new option, you can select Available meters to add. F5 is added to the upper left and F6 to the upper right. Under Left column and Right column, you can choose how the information is displayed, such as LED, Bar (progress bar) and Text (text mode), which can be set according to your preferences # 2. Display options selects the content to be displayed, and displays it by space x. After selection, press F10 to save # 3. I don't think it is useful to set the color of the Colors interface. The function of Colums is to add or cancel the contents to be displayed. After selection, F7 (move up), F8 (move Down), F9 (cancel display, F10 (Save changes)) PPID and PGRP are added here, and the information is displayed according to each person's needs. * * F3 search process * * you can enter the search mode directly by pressing F3 or typing "/" directly in the interface. The search is based on the process name, and the searched process will be marked with the set color for easy viewing. * * F4: filter * * is equivalent to fuzzy search and is not case-sensitive. After entering the content to be searched below, the interface only displays the content to be searched. It is more convenient to view * * F5: display * * F6 in a tree format: after pressing F6, it will jump to the tree display interface, allowing you to choose how to sort. Under Sort by, select what you want to sort F7 nice F8: adjust the process nice value * * F7 to decrease the nice value (increase the priority), F8 increase the nice value (decrease the priority), select a process, press F7 or F8 to increase or decrease the nice value, and the nice value ranges from-20 to 19 * * F9: kill the process. Select a process and press F9 to kill the process. Very convenient * * F10: exit the htop** to this point.
