使用 bash 创建 email 模板的更好方法

Question

Using bash to create an email template:

#!/bin/bash
VAR1="today is "
VAR2="a good day"

echo "Good Morning" >> /tmp/email_template
echo $VAR1$VAR2 >> /tmp/email_template
echo "Best regards" >> /tmp/email_template
cat /tmp/email_template|mutt -s "Hello!" destination@gmail.com

is there something more clean to create an email template?

Answer 1

You can use a HERE doc as mentioned by a comment above or you can use a block like this:

#!/bin/bash
VAR1="today is "
VAR2="a good day"

{
echo "Good Morning"
echo "$VAR1$VAR2"
echo "Best regards"
} | mutt -s "Hello!" 'destination@gmail.com'

Answer 2

This is how you would do it using the HERE doc approach:

#!/bin/bash
VAR1="today is "
VAR2="a good day"

mutt -s "Hello!" destination@gmail.com <<EOF
Good Morning
$VAR1$VAR2
Best regards
EOF
