使用shell脚本向电子邮件组发送电子邮件

Question

下面是我的shell脚本,工作正常.

#!/bin/bash

DATE_YEST_FORMAT2=`perl -e 'use POSIX qw(strftime); print strftime "%Y%m%d",localtime(time()- 3600*96);'`
echo $DATE_YEST_FORMAT2

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';"`

echo "Total items purchased: `echo $QUERY1 | awk '{print $1}'`"
echo "Total Items MissingorMismatch: `echo $QUERY1 | awk '{print $2}'`"
echo "Error Percentage: $QUERY2"

我在下面运行上面的shell脚本 -

sh -x test.sh

问题陈述:-

从上面的shell脚本中,我从最后三个echo语句中得到以下三件事 -

Total items purchased
Total Items MissingorMismatch
Error Percentage

我需要通过电子邮件将上述所有这三件事发送到我们的电子邮件群组DL-host@company.com中shell script,或者假设10 email list我需要发送具有相同内容和主题的电子邮件,然后我想,我可以存储所有这些10个电子邮件列在一些变量中,只是从那里读取并继续发送,对吗？这有可能吗？我正在考虑下面这样的电子邮件结构,只是非常简单.

学科

测试数据

邮件正文

Total items purchased:-    Some Number
Total Items MissingorMismatch:-   Some Number
Error Percentage:-   Some Number

任何想法将不胜感激.

更新,在尝试了larsks建议之后,我只收到电子邮件中的最后一个echo语句,意味着只有一个错误百分比,而不是全部三个:

#!/bin/bash

DATE_YEST_FORMAT2=`perl -e 'use POSIX qw(strftime); print strftime "%Y%m%d",localtime(time()- 3600*96);'`
echo $DATE_YEST_FORMAT2

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';"`

echo "Total items purchased: `echo $QUERY1 | awk '{print $1}'`"
echo "Total Items MissingorMismatch: `echo $QUERY1 | awk '{print $2}'`"
echo "Error Percentage: $QUERY2" | mail -s "Test Data" rj@host.com

Answer 1

您通常使用该/bin/mail程序从shell脚本发送电子邮件.您在命令行和邮件正文上提供主题和收件人stdin.例如,在您的脚本中,您可以执行以下操作:

{
echo "Total items purchased: `echo $QUERY1 | awk '{print $1}'`"
echo "Total Items MissingorMismatch: `echo $QUERY1 | awk '{print $2}'`"
echo "Error Percentage: $QUERY2"
} | mail -s "Test Data" DL-host@company.com

您还可以将现有脚本的输出通过管道mail传输(如果您不想修改脚本,或者您只想发送邮件somtimes):

<your script> | mail -s "Test Data" DL-host@company.com

您可以在命令行上指定多个收件人,因此:

... | mail -s "Test Data" address1@company.com address2@company.com

等等.
