Linux disk space email alert

gistfile1.sh

#!/bin/bash
# www.fduran.com
# script that will send an email to EMAIL when disk use in partition PART is bigger than %MAX
# adapt these 3 parameters to your case
MAX=95
EMAIL=alert@example.com
PART=sda1

USE=`df -h |grep $PART | awk '{ print $5 }' | cut -d'%' -f1`
if [ $USE -gt $MAX ]; then
  echo "Percent used: $USE" | mail -s "Running out of disk space" $EMAIL
fi

fantastic script - thank you!

I had to use
df -hP
To get posix format as the $PART was making normal output wrap to a new line.

grateful

Excellent, thank you!

Hi I have similar script like yours:

if [ $USED -gt $LIMIT ]

#If used space is bigger than LIMIT

then

  du -sh ${DIR}/* | $MAILX -s "$SUBJECT" "$MAILTO"

#This will print space usage by each directory inside directory $DIR, and after MAILX will send email with SUBJECT to MAILTO

fi

But getting [: too many arguments error.

Could you please help?

atural91 it won't work on newer distros of linux, have tried on Ubuntu 18.04, got the same error, plenty of software which starts with Ubuntu on boot and sends out emails, just search Github.
