How to Manage Linux Processes With htop – Guide

The tool htop is a Linux tool that allows you to monitor the CPU and memory usage of your processes. It was created to replace the Unix command-line utility “top” and is much easier to use for simple, common tasks.

Htop is a tool that provides a full list of running processes, rather than just the most resource-intensive ones. It can display processes as a tree, and uses colors to provide resource usage statistics. Additionally, htop is an interactive mouse and keyboard. This makes it easy to find and eliminate annoying processes without having to enter their PIDs.

The first mode is the default, which shows the CPU usage as percentages of total system resources. The second mode shows the CPU usage as percentages of available cores. In the upper left corner, CPU usage is represented by percentages using different colored bars for different types of processes, and the CPU core is indicated by the number of bars. Two CPU metric modes are The first mode is the default, which shows the CPU usage as percentages of total system resources. The second mode shows the CPU usage as percentages of available cores. ..

The colors given below are the standard mode colors for use on a computer monitor. They are the colors that are used by most programs and web pages. ..

The blue thread is a low priority thread, which means that it is not as important as other threads. This means that it may be ignored or have less attention given to it. ..

Theft time is the amount of time that has elapsed since the theft occurred. Guest time is the amount of time that was spent by the thief on the property.

The CPU Usage bars show the amount of memory used by processes. Memory usage and swap are both present below the CPU Usage bars. This display shows how much memory is used by each process.

The RAM consumption by memory pages is a measure of the amount of memory used to store data in a computer. This figure can be used to determine the amount of RAM that is required for a specific application or system.

The average RAM consumption per buffer pages is around 512KB. ..

Cache pages are used to store data in the RAM. When a page is accessed, the cache stores the data in memory and then retrieves it from the RAM when it needs to be used. This can save time when accessing data because the data is not stored on disk.

Htop is a free utility that can be used to view and manage processes on a computer. Select the process you want to kill and press F9 or k to display the signals menu. There, you will find a list of signals for the process. Choose “SIGKILL” to kill the chosen process and press enter. Here, we kill the signal with PID 1989. For multiple processes, select a process and click on the spacebar which will mark the selected process. After that, the changed tag of the process will change color and then scroll through the list to tag multiple processes. Press F9 to kill all marked processes. ..

In this menu, there are different sorting options to choose from to sort the output. You can press F6 and select the criteria of your choice to sort the output by default.

Press F5 to display the process in tree order or hierarchical order. ..

Press the F4 key to filter the process. ..

The ryslogd process is found in the /usr/bin path.
