The shell script realizes the hard disk space and the table space usage statistics and the mail informs the _linux shell

Copy Code code as follows:

#/bin/bash
#该脚本用于统计硬盘空间和表空间的使用情况, and Mail out
#初始化环境变量
Source/home/oracle/.bash_profile
#获得本机ip
ip= '/sbin/ifconfig eth0 | grep bcast | Cut-d:-F 2 | Cut-d ""-F 1 '
#切换到本脚本目录
cd/home/oracle/shell/
#删除之前该脚本产生的日志文件
RM-RF $ip. txt
#统计硬盘空间
Echo-e "Hello!"
$IP statistics are as follows: \ n ">> $ip. txt
echo "Hard disk space statistics:" >> $ip. txt
