注：部分系統參數稍有差異，最好看幫助

1) 無郵件正文

mail -s "主題" 收件地址

mail -s "測試"  [email protected]

2) 有郵件正文

mail -s "主題" 收件地址< 文件(郵件正文.txt)

mail -s "郵件主題"  [email protected] < /data/findyou.txt

echo "郵件正文" | mail -s 郵件主題 收件地址

echo "郵件正文內容" | mail -s "郵件主題"  [email protected]

cat 郵件正文.txt | mail -s 郵件主題 收件地址

cat  /data/findyou.txt | mail -s "郵件主題"  [email protected]

3) 帶附件

mail -s "主題" 收件地址 -a 附件 < 文件(郵件正文.txt)

mail -s "郵件主題"  [email protected] -a /data/findyou.tar.gz < /data/findyou.txt
