Below is my Bash Shell Script from which I am executing my two Hive SQL Queries which is working fine. And I am calculating Error Percentage in this Bash Shell Script.
#!/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 rj@host.com rj@host.com <<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
Problem Statement:-
I will be getting Error Percentage number in $QUERY2. I need to make a Simple Pie Graph that can show Error Percentage and No Error Percentage by using the number from $QUERY2 just like below graph using Bash Shell Script.
I am running SunOS. Is this possible to do in Bash Shell script? Any thoughts will be appreciated.
Update:-
Below is the Shell Script that I am using, that I created using vi editor.
1 #! /bin/bash

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

Error that I got after running the above shell script as sh -x chart.sh-
bash-3.00$ sh -x chart.sh
chart.sh: syntax error at line 3: `TEMP=$' unexpected
Any thoughts will be appreciated.
Another Update:-
After the below suggestions, when I tried something like this-I got another error.
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
mktemp: failed to create file: /tmp/chart
+ TEMP=
+ QUERY1=36
+ QUERY2=64
+ cat
chart.sh: line 6: $TEMP: ambiguous redirect
Another Update: Made Some Progress I guess. Not sure where the output files will be going? Or it will open into a browser?
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
+ TEMP=/tmp/chart
+ QUERY1=36
+ QUERY2=64
+ cat
++ uname
Solução
A very simple way of creating a Google Chart:
#! /bin/bash
TEMP=$(mktemp -t chart.XXXXX)
QUERY1=36
QUERY2=64
cat > $TEMP <<EOF

if you save it as chart.sh then run it as
$ bash -x chart.sh
or
$ chmod +x chart.sh
$ ./chart.sh
which gives you something like
Notice that you only need bash and an Internet connection, there's nothing to install.
mktemp should be available in Solaris (http://docs.oracle.com/cd/E23824_01/html/821-1461/mktemp-1.html). If you don't have it just set TEMP to whatever file you want the HTML output to be.

A simple way to create a pie chart in only shell, is to generate an svg image.
A simple/small program to generate other image types is Ploticus. http://ploticus.sourceforge.net/doc/welcome.html
There is probably no native way of doing it, so I would assume that your best bet is to get a third party tool installed, like-
