Hello. First time here. Site looks really cool, with lots of great info. However, I need some scripting help:

In a nutshell:

I am in need to create a script that queries how large a partition is and when it hits a certain percentage (say 90%) it will execute another script that tars up certain files (or they could just be part of the same script). I would create a cronjob that runs this script once a day.

I have the script that tars up the files I need, sets permissions, etc. (btw, the files in question are audit logs). I just need the part that runs something like a df -h and takes the use percentage of the /var partition in that query and if that percentage is greater than/ equal to 90%, it kicks off the tar script.

Here is a sniplet of the df -h with just the /var partition shown:


So, when the cronjob sees that the Use% is >= 90%, it would kick off the tar script...if not above 90%, it closes.

Thanks.

Hi,
the script u have asked may be like this.

#!/bin/bash
a=$( df -h | grep -i "var" | awk '{print $5}' | awk 'sub(".$","")')
if [ $a -ge 90 ]
then
exit
else
echo "Run Tar Script" # you may put the path of tar script here
fi

Thanks! I'll give this a try.

arvind.lotus,

I wanted to relay that I tried your recommendation and it works like a charm (I just switched the script path and exit around so it would run the script if it is >= 90% vs. exiting).

Thanks again!
