Shell script for monitoring disk usage (local + Remote)

Monitordisk. sh: Copy codeThe Code is as follows :#! /Bin/bash
# Updated: PM By: leif (liangliwen@163.com)
EMAIL =/usr/local/bin/email
/Bin/df-h>/tmp/df.txt

USE = 'df-H | grep-o [0-9] * % | grep-o '[0-9] \ +''

For I in $ USE
Do
If ($ I> 95 ))
Then
$ EAMIL-s "WARNING Low disk space for $ I" liangliwen@163.com break
Fi
If ($ I> 90 ))
Then
$ EMAIL-s "Low disk space for $ I" liangliwen@163.com fi
Done

/Bin/rm-f/tmp/df.txt

To achieve this, any partition uses 90% to send an EMAIL to the specified recipient, and then sends a warning (warning) on the subject of the EMAIL to 95%, indicating that the EMAIL sending program EMAIL is used, is to download the installation from the http://www.cleancode.org/projects/email, more flexible.

Place the shell on crontab as needed to regularly check disk Conditions

The following is a supplement:

We can use cron to schedule script execution at a fixed interval. For example, we can add such entries to the crontab to automatically run the script at ten o'clock A.M. every day:

00 10 ***/home/sh/disklog. sh/home/log/diskusg. log

Run the crontab-e command to add and save the preceding line.

You can also manually execute:

$./Disklog. sh
