HTML郵件發送Oracle表空間佔用百分比

前段時間寫了一個監控Oracle表空間百分比的shell腳本，功能是實現了，但是發送的報警郵件內容排版不是很好，今天偷巧稍微改動了下，排版還不錯。不多說了，詳情腳本：

#!/bin/bash
#
# Description: Check local Oracle database tablespace usage rate,
# It will send mail to admin when then usage rate more than 95%.
#
logfile='/tmp/tablespace_check.log'
tmpfile='/tmp/tablespace_check.txt'
