下面是我的bash shell脚本，我正在从中执行两个运行良好的配置单元sql查询。我正在计算这个bash shell脚本中的Error Percentage。
#!/bin/bash
QUERY1=`hive -e "
set mapred.job.queue.name=hdmi-technology;
SELECT SUM(total_items_purchased), SUM(total_items_missingormismatch) from lip_data_quality where dt='$DATE_YEST_FORMAT2';"`
QUERY2=`hive -e "
set mapred.job.queue.name=hdmi-technology;
SELECT 100 * SUM(total_items_missingormismatch*1.0) / SUM(total_items_purchased) FROM lip_data_quality where dt='$DATE_YEST_FORMAT2';"`
mailx -s "LIP Data Quality Report for $DATE_YEST_FORMAT1" -r [email protected] [email protected] <<EOF
Data Successfully loaded into LIP_DATA_QUALITY table
Total Items Purchased: `echo $QUERY1 | awk '{print $1}'`
Total Items MissingorMismatch: `echo $QUERY1 | awk '{print $2}'`
Error Percentage: $QUERY2
EOF
问题陈述：
我将在
Error Percentage中得到$QUERY2数字。我需要制作一个简单的饼图，可以使用Error Percentage中的数字来显示No Error Percentage和$QUERY2，就像下面使用bash shell脚本的图一样。我正在运行
SunOS。在bash shell脚本中可以这样做吗？任何想法都会被感激的。更新：
下面是我正在使用的shell脚本，它是我使用
vi editor创建的。 1 #! /bin/bash

3 TEMP=$(mktemp -t chart)
4 QUERY1=36
5 QUERY2=64
6 cat > $TEMP <<EOF

在以
sh -x chart.sh的形式运行上述shell脚本后出现的错误-bash-3.00$ sh -x chart.sh
chart.sh: syntax error at line 3: `TEMP=$' unexpected
任何想法都会被感激的。
另一个更新：
根据下面的建议，当我尝试这样做时，我又犯了一个错误。
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
mktemp: failed to create file: /tmp/chart
+ TEMP=
+ QUERY1=36
+ QUERY2=64
+ cat
chart.sh: line 6: $TEMP: ambiguous redirect
另一个更新：我想已经取得了一些进展。不确定输出文件要去哪里？或者打开浏览器？
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
+ TEMP=/tmp/chart
+ QUERY1=36
+ QUERY2=64
+ cat
++ uname
最佳答案
创建Google Chart的一种非常简单的方法：
#! /bin/bash
TEMP=$(mktemp -t chart.XXXXX)
QUERY1=36
QUERY2=64
cat > $TEMP <<EOF

如果将其保存为
chart.sh，则将其运行为$ bash -x chart.sh
或
$ chmod +x chart.sh
$ ./chart.sh
给了你一些
注意，您只需要
bash和一个internet连接，就不需要安装任何东西。mktemp应该在solaris中可用（http://docs.oracle.com/cd/E23824_01/html/821-1461/mktemp-1.html）。如果没有，只需将temp设置为所需的html输出文件。关于linux - 使用Bash Shell脚本制作简单的饼图，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/11917818/
