Sendmail bash 脚本，用新行连接字符串

Question

I am concatenating xmsg and links to new variable body . What I am trying to accomplish is when email send out. I want new line between xmsg and `links

xmail="sendmail"

links="<a href="https://www.xxx>Unsubscribe</a>"
xmsg='Hello World'
body=$xmsg \n $links

### Compose emails one at a time, per loop.
"$xmail" "$email" << EOF
subject:$xsub
from:$xfrom
Content-Type: text/html;
Mime-version:1.0;
$body
EOF

Excepted output in email

Hello World
Unsubscribe

I tried almost everything here . But none works, either I get blank body in email or all in same line

Answer 1

You're sending an HTML email and need to use <br> instead of \\n .

You need to enclose the whole string in double quotes. Try body="$xmsg <br> $links"
