Script to check if a space partition is full

We can use "df" to check if a Linux server space is full or not. Script below will send an email out when when it reaches the threshold. 

#Script to check if a space partition is 80% full

threshold=80

shareLoc='/path/to/partition'       # such as the one for $APPLCSF of Oracle EBS

spacesize=`df -h | grep $shareLoc | awk '{print $5}' | tr -cd '[[:digit:]]'`

spacepercent=`df -h | grep /tmpshrs/ebsarupgradeTEMP | awk '{print $5}'`

freesize=`df -h | grep /tmpshrs/ebsarupgradeTEMP | awk '{print $4}'`

if [ $spacesize -gt $threshold ]; then

echo "$shareLoc is too large" | mailx -s "Warning: $shareLoc is ${spacepercent} full" email@address.com

echo "Email sent."

else

echo "$shareLoc has $freesize free. Used $spacepercent "
