以下是我的Bash Shell腳本，我正在執行我的兩個Hive SQL查詢工作正常。我正在計算這個Bash Shell腳本中的Error Percentage。使用Bash Shell腳本製作一個簡單的餅圖
#!/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: $QUERY2
EOF
問題陳述： -
我將在$QUERY2越來越Error Percentage號。我需要製作一個簡單的餅形圖，通過使用$QUERY2中的編號，可以顯示Error Percentage和No Error Percentage，就像下圖使用Bash Shell腳本一樣。
我正在SunOS。這是可能在Bash Shell腳本中做到的嗎？任何想法將不勝感激。
更新： -
下面是shell腳本，我使用，我用vi editor創建。我運行上面的外殼腳本sh -x chart.sh後得到
1 #! /bin/bash

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

錯誤 -
bash-3.00$ sh -x chart.sh
chart.sh: syntax error at line 3: `TEMP=$' unexpected
任何想法將不勝感激。
另一個更新： -
下面的建議後，當我試圖這樣的事情，我有另一個錯誤。
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
mktemp: failed to create file: /tmp/chart
+ TEMP=
+ QUERY1=36
+ QUERY2=64
+ cat
chart.sh: line 6: $TEMP: ambiguous redirect
另一個更新：取得了一些進展我猜。不知道輸出文件將在哪裏？或者它會打開瀏覽器？
bash-3.00$ bash -x chart.sh
++ mktemp -t chart
+ TEMP=/tmp/chart
+ QUERY1=36
+ QUERY2=64
+ cat
++ uname
