我想在 shell 脚本中以 HTML 电子邮件的附件形式发送员工详细信息 excel 表。我尝试使用下面的代码，但无法做到。

请帮忙。

    if [[ -f /x/project/Emp_Report.xlsx ]]; then

    echo "Employee Report exists !!"
    (
        echo "From: abc@gmail.com"
        echo "To: xyz@gmail.com"
        echo "cc: pqr@gmail.com"
        echo "Subject:Employee Report"
        echo "Content-Type: TEXT/HTML, multipart/mixed, text/html, application/octet-stream"
        echo "Content-Transfer-Encoding: base64"
        echo "Content-Disposition: attachment;filename=/x/project/Emp_Report.xlsx"
        echo "<html>"
        echo "<body>"
        echo "<p>Hi Team,</p>"
        echo "<p>Please find the Employee details in attachment.</p>"
        echo "<p>In case of any queries, kindly reach out to 'abc@gmail.com'</p>"
        echo "<b>Regards,</b><br>"
        echo "Abc"
        echo "</body></html>"
    ) |  /usr/sbin/sendmail -t

  fi

在标题和正文之间需要一个空行。
附件需要 MIME 电子邮件，因此您需要边界

以下是我工具库中发送电子邮件的 shell 脚本的 sn-p：您需要更改 text/plain

    local boundary="_====-boundary-${$}-$(date +%Y%m%d%H%M%S)-====_"

    {
        echo "From: $from"
        echo "To: $to"
        echo "Cc: $cc"
        echo "Subject: $subject"
        echo "Content-Type: multipart/mixed; boundary=\"$boundary\""
        echo "Mime-Version: 1.0"
        echo
        echo "This is a multi-part message in MIME format."
        echo
        printf -- "--%s\n" "$boundary"
        echo "Content-Type: text/plain; charset=ISO-8859-1"
        echo
        echo "$body"
        echo
        for filename in "${attachments[@]}"; do
            # attach it if it's readable and non-zero size
            if [[ -r "$filename" ]] && [[ -s "$filename" ]]; then
                printf -- "--%s\n" "$boundary"
                echo "Content-Transfer-Encoding: base64"
                echo "Content-Type: application/octet-stream; name=$(basename "$filename")"
                echo "Content-Disposition: attachment; filename=$(basename "$filename")"
                echo
                base64 "$filename"
                echo
            fi
        done
        printf -- "--%s--\n" "$boundary"
    } | /usr/lib/sendmail -oi -t
