Powershell script: Powershell equivalent of Linux top

01 March,2016 by Jack Vamvas


One thing I like about Linux is the top command. The linux top command displays in a continious stream cpu movements. This real-time display is very useful when you're trying to identify any unusual patterns in cpu, or trying to identify the highest user.

I started thinking about you would have a similar structure using powershell. Getting the cpu information is straightforward.

 
Get-Process or ps will display the information with the headers:

Handles  NPM(K)    PM(K)      WS(K) VM(M)   CPU(s)     Id ProcessName


Thats's easy. But to view any movements I need to continiously hit the refresh button. There are better things to do , particuarly if you can program the refresh sequence.

In Powershell you can set off a command and it will refresh without you needing to continiously click in the button. Replicating the same behaviour as Linux top is just a few extra keystrokes, and the effect is similar

Here is an example of Powershell scripting , that will display the top 10 processes based on CPU and refresh every 3 seconds. You can adjust the refresh rate and sort as it suits your requirements

 

while (1) {Get-Process | sort -desc cpu | select -first 10; 
sleep -seconds 3; cls; 
write-host "Handles  NPM(K)    PM(K)      WS(K) VM(M)   CPU(s)     Id ProcessName"; 
write-host "-------  ------    -----      ----- -----   ------     -- -----------"}
