下面是我用来创建 PIE Graph 的 shell 脚本。
#! /bin/bash
TEMP=$(mktemp -t chart.html)

QUERY2=64

// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);

function drawChart() {

var data = new google.visualization.DataTable();

data.addRows([

['No Error Percentage', $QUERY2]

// Set chart options
var options = {'title':'Errors',

问题陈述:-
我将上面的文件保存为chart.sh
. 每当我尝试将上述chart.sh
文件运行为sh -x chart.sh
我总是得到错误 -
syntax error at line number 3: `TEMP=$' unexpected
但是当我尝试运行上述sh
文件时 -
bash -x chart.sh
那我什么都没有error
。为什么会这样?我的 shell 脚本有什么问题吗,假设如果我需要像sh -x chart.sh
往常一样运行它,那么我需要在我的 shell 脚本中进行哪些更改?
我正在跑步SunOS
