为什么sendmail发送空白文本文件？

我想创建一个能够通过电子邮件发送日志文件的脚本。现在的问题是我通过电子邮件收到的文本文件是空白的。是哪一部分出了问题？

MYSQL_SLOW_LOG_USER="****"
MYSQL_SLOW_LOG_PASSWORD="*****"

SLOW_LOG="/var/log/mysql-slow.log"

cat <<EOF | mysql -u $MYSQL_SLOW_LOG_USER -p$MYSQL_SLOW_LOG_PASSWORD
SET GLOBAL log_queries_not_using_indexes = 'OFF';
SET GLOBAL slow_query_log = 'OFF';
FLUSH SLOW LOGS;
EOF

cat $SLOW_LOG > /tmp/corpsoDB.txt

recipient="[email protected]"

(
cat - <<END
Subject: MySQL Slow Query Log Report-Corpso
Content-Type: multipart/mixed; boundary="-omgemailslikewhoa"

GET ON IT.

---omgemailslikewhoa
Content-Type: text/plain; name="corpsoDB.txt"
Content-Disposition: attachment; filename="corpsoDB.txt"
END

cat /tmp/corpsoDB.txt

cat <<END
---omgemailslikewhoa--

END
) | /usr/sbin/sendmail -i -- $recipient

/tmp/corpsoDB.txt

/usr/sbin/mysqld, Version: 5.7.31-log (MySQL Community Server (GPL)). started w$
Tcp port: 0  Unix socket: /var/lib/mysql/mysql.sock
Time                 Id Command    Argument

三通/tmp/sendmail-input.txt

Subject: MySQL Slow Query Log Report-Corpso
Content-Type: multipart/mixed; boundary="-omgemailslikewhoa"

---omgemailslikewhoa
Content-Type: text/plain
Content-Disposition: inline

GET ON IT.

---omgemailslikewhoa
Content-Type: text/plain; name="corpsoDB.txt"
Content-Disposition: attachment; filename="corpsoDB.txt"
/usr/sbin/mysqld, Version: 5.7.31-log (MySQL Community Server (GPL)). started w$
Tcp port: 0  Unix socket: /var/lib/mysql/mysql.sock
Time                 Id Command    Argument
---omgemailslikewhoa--

这是我仅从电子邮件中收到的内容 https://drive.google.com/file/d/1jnNuezyWxYAdNW_ZZ9ZvG1MG3ZJFLaBc/view?usp=sharing

内容处置：附件；文件名=“corpsoDB.txt”
结尾

猫/tmp/corpsoDB.txt

您应该在正文部分标题和正文部分内容之间生成换行符。
