How do you read htop commands?

In a nutshell, htop is a useful command-line tool in the Linux environment to determine the cause of load by each process. It is similar to Task Manager in the Windows OS environment. It can be used to troubleshoot and kill a process that is utilizing excessive server resources. That's it!

What is the purpose of htop?

htop uses color and gives visual information about processor, swap and memory status. htop can also display the processes as a tree. Users often deploy htop in cases where Unix top does not provide enough information about the system's processes. htop is also popularly used interactively as a system monitor.

What do the colors in htop mean?

Dark Blue – Indicates CPU percentage used by low priority processes. Low processes in htop are indicated by an exit value of greater than 0. Green – shows processes running as regular users in the system. Red – shows kernel threads. Aqua Blue – shows virtualized processes.

What is the difference between R and S in htop?

While within htop it is denoted as only an “S”, it stands for process state. Here are the values you might encounter within it: R: the process is currently running or on a run queue waiting to run. S: the process is in interruptible sleep (waiting for an event or condition to happen).

Does htop show cores or CPUs?

Run top or htop command to obtain the number of CPUs/cores in Linux.

Is there an htop for GPU?

Nvtop stands for Neat Videocard TOP, a (h)top like task monitor for AMD, Intel and NVIDIA GPUs. It can handle multiple GPUs and print information about them in a htop familiar way.

Is htop better than top?

top is the older command and it comes preinstalled on all Linux distros. htop is newer and it adds color and gives a more interactive user interface than top. In other words, htop provides a slightly better user experience, but it's not a standard command you'll find on all Linux systems.

Does htop show physical cores?

cpuinfo show the actual cores while htop/top show both cores and thread as cores. You most likely have 4 cores and 4 threads that's why.

What is difference between top and htop?

While top focuses on the processes that consume the most system resources, htop shows all running processes. htop also provides a rich-colored display and visual information about processor, swap, and memory status. It also provides a cursor-controlled interface for sending signals to processes.

Does htop show all processes?

Htop is a free (GPL) ncurses-based process viewer for Linux. It is similar to top, but allows you to scroll vertically and horizontally, so you can see all the processes running on the system, along with their full command lines.

What is green in htop?

Blue = Low priority threads. Green = Normal priority threads. Red = Kernel threads.

What does nice mean in htop?

nice is used to invoke a utility or shell script with a particular CPU priority, thus giving the process more or less CPU time than other processes. A niceness of -20 is the highest priority and 19 is the lowest priority. The default niceness for processes is inherited from its parent process and is usually 0. nice.

How to analyse top command in Linux?

Top's first line, top, shows the same information as the uptime command. The first value is the system time. The second value represents how long the system has been up and running, while the third value indicates the current number of users on the system. The final values are the load average for the system.

What are the interactive commands in htop?

INTERACTIVE COMMANDS. The following commands are supported while in htop: Arrows, PgUP, PgDn, Home, End Scroll the process list. Space Tag or untag a process. Commands that can operate on multiple processes, like "kill", will then apply over the list of tagged processes, instead of the currently highlighted one.

What information does the Linux command htop allow access to?

It displays a complete list of processes running on the system and gives information on CPU use, memory and Processor. With the help of htop, we can sort the processes depending on CPU, memory use, and processes run by the user. There are various commands and options available for the htop command.

What is difference between top and htop?

While top focuses on the processes that consume the most system resources, htop shows all running processes. htop also provides a rich-colored display and visual information about processor, swap, and memory status. It also provides a cursor-controlled interface for sending signals to processes.

How do I find the top 5 largest files in Linux?

Listing Files In Size Order Using the ls Command in Linux

To list the directory contents in descending file size order, use the ls command along with the -IS argument. You will see the larger files at the top of the list descending to the smallest files at the bottom.

How do I find top 10 CPU utilization in Linux?

Use ps Command to Find Top Processes by Memory and CPU Usage

ps is a Linux command-line utility with many options that helps you to display output in different formats. You can use the ps command with –sort argument to sort the output by memory and CPU usage.
