Htop is currently the most popular top alternative thanks to its interactive menu and the ability to scroll vertically and horizontally. There are plenty of top alternatives, such as Htop, Vtop, Gtop, Gotop, and many more – although I won't cover all these in this article. To save all the running top command results into a file, you can use these commands: top -n 1 -b > top-processes.txt top Alternatives You can see that the CPU utilization is initially very high, although it starts to decrease as VSCode loads in all my extensions and the Intellisense. Now you know what was hogging up your CPU – that pesky little while loop that kept running infinitely!įor example, when I filter my processes when I open VSCode, here's what I see: In order to sort all your Linux processes by how much CPU they use, you would need to press the SHIFT + P keys in order to sort them in top.

Showing how to change the refresh interval How to Sort Processes by CPU Utilization If you would like to increase the interval or decrease it, you can press d while you are in the top interactive shell in order to set a desired time. We'd get the following (which shows processes being run under the "brandgrim" user): How to Change the Refresh Intervalīy default, the screen refresh interval for top is set to 3.0 seconds. If we were to try this command, on the other hand: top -u brandgrim Which lists out the processes that are being run under the "root" user. The -u flag specifies which processes should be listed depending on what user you specify.įor example, we saw that under the USER column there was "root" and "brandgrim", so if we were to try this: top -u root Top has so many unique flags and commands it may seem overwhelming to know which one to use, although there are some flags that are useful right off the bat. Showing the "Summary of Less Commands" in top Useful Flags and Commands When you are in the interactive shell of top you can press h to bring up the Summary of Less Commands which is a list of all the commands top has to offer. COMMAND: The name of the command that actually started the process.+TIME: Depicts the total CPU time that the task has used since the task started.SHR: This number represents the Shared Memory size used by a specific task.RES: How much RAM the process is actually using, measured in KB.
VIRT: The total virtual memory used by the task.PR: This number shows the process priority – the lower the number is, the higher priority.Root is, well, the root of the system running that process, whereas "brandgrim" (me!) is the user running that process. USER: Shows which user is running what taskįor example, you see "root" and "brandgrim".PID: Shows the task's unique process ids.To leave top press q on your keyboard to exit the interactive shell. Usually, this command shows a summary of the information on your system that's currently being run/managed by the Linux kernel. Thats pretty neat – the top program shows a dynamic list of all the running processes going on in your Linux system. If you were to try this command in your terminal, you would see this: The top (table of processes) command in Linux will display all the system processes.

MacOS Activity Monitor Windows Task Manager What is the Linux Equivalent? You may be used to using the Activity Monitor in MacOS or the Task Manager for Windows to see the current processes running on your system.īut for those running Linux, if that includes a dual boot, virtual box, or even WSL2, you could use a useful Linux command to inspect and look at all the current processes going on in your operating system.
