filepath=xxxxx
email_result=$(cat ${filepath})
echo -e $email_result

输出不会换行。
后来搜索一番发现了解决办法

filepath=xxxxx
email_result=$(cat ${filepath})
echo -e "$email_result"

没错加个引号就好了。
我最终使用的代码,

filepath=xxxxx
email_result=$(cat ${filepath})
email_content="下载地址：xxxx"'\n'"更新日志："'\n'"$email_result"
sendEmail -f ${email_sender} -t ${email_reciver} -s ${email_smtphost} -u ${email_title} -xu ${email_username} -xp ${email_password} -m "$email_content" -a ${file_path}  -o message-charset=utf-8
