Use Google APIs in Linux to plot the CPU usage of processes

Thanks to grapeot for its inspiration, powershell is used to draw a pie chart showing the CPU usage of processes. I also made a Linux version. I am not familiar with gnuplot and do not know if I can draw a pie chart. Here I use a simple and easy-to-use Google API. First, let's take a look at the static pie chart of the Google chart API:

 

 

Let's take a look at the pie chart in the visualization API just released by Google recently (click here to view the actual effect. below is just, I don't know howArticleEmbedded in JSCode......) :

 

The following is the bash script code (this editor does not support bash code highlighting ...... I will use PS highlight instead, but it's strange ......) :

1 # ! /Bin/bash
2
3 Function Gen_chart (){
4 Chlorophyll = " Chlorophyll = $1 " ; CHD = " CHD = T: $2 " ; Shift
5 While [ $ # -GT 0]; do chlorophyll = "$ {chlorophyll} | $1"; CHD = "$ {CHD}, $2"; shift; done
6
7 # Url = "http://chart.apis.google.com/chart? CHS = 500x200 & CHT = P3 & chtt = Top + 10 + processes + running & $ chlorophyll & $ CHD"
8 URL = " Http://home.ustc.edu.cn /~ Stephen 1/pschart.html? Chtt = Top + 10 + processes + running & $ chlorophyll & $ CHD "
9 Chrome " $ URL "   2 >/ Dev / Null
10 }
11
12 Gen_chart 'ps - EO " % C "   -- Sort =- Pcpu | Head - N 11   | Tail - N 10 `
13

The principle is very simple. First, call the ps command to sort and print the CPU usage of each process, and then extract the first 10 items. Then, let's hand over the rest to Google API :-)

Thank you for sharing grapeot. I'm amazed at the power of powershell. I thought that PS was just an upgraded version of CMD, but I only added some gadgets. Now I find that my intuition is wrong again. From the introduction of grapeot, I think the essence of PS lies in the object-oriented idea. commands are not transmitted between texts, but objects. If PS can create a pipeline that supports object passing, it may be more powerful!

Microsoft not only strives to lower the threshold for end users to use computers and enhance user experience, but also strives to lower the threshold for developers, which also enables it to have a large number of development teams in the market. The threshold for Linux development is too high. However, the advantage is that the code quality is generally high,ProgramThe execution efficiency is high, but the user is too poor ......

Who can tell me how to insert JavaScript code directly in this blog post and run it? In addition, if you want to add a bash code block to the editor, who should you respond? Thank you for your support ~
