Use monitoring space under Linux SuSE and send email to inform __linux

1. Select directory to create script file:

2. Give script executable permissions

3.vim test.sh Edit Script, paste the following:

#----Start----


#获取目录空间大小
sizeall=$ (df-h | grep Home | awk ' {print $} ')


#获取目录空间已使用大小

#获取目录空间可用大小
sizeavail=$ (df-h | grep Home | awk ' {print $} ')


#获取目录已使用百分比

4. Save exit, add timer, command crontab-e

I'm here configured to execute the script once every 30 minutes

5. This is done, for testing, can be configured to perform once per minute, and then to see the log output.
