Shell script to check the disk space on the server.

I wrote a script to check the disk space on the server, and if any partition is found to be using more than 90%, it will sent an email to the server admin.

I later added this script as a cronjob.
Now this cron runs every day and it really helped us to deal with the disk space issues on the server.

Create a file: diskcheck.sh

Code:

#!/bin/bash
hos=`hostname`;
spc="";
spc=`df -h|awk '/dev/{ print $5,$6 }'|grep -e [9][0-9]% -e 100%`
if [ -z "$spc" ]
then :
else
echo "$spc Please login to server and check"|mail -s "Disk Check on $hos" your-email@domain.com
fi
