Hi

I am looking for a shell script to delete old files whenever storage limit is crossed for a folder. That would be great if anyone point me in the right direction in finding a simple way to do this?

Thanks in advance

Hello there :-)

Can you please provide more information about the place that you want these files be deleted from?

For example, do you need the script to delete files form a specific folder or what's exactly the point?


Thanks.

Here is the right direction:

1. Write a script that has a way to determine that a specified storage limit is exceeded.

2. If (1) is true, locate the oldest files and delete them.

Start coding and if you have difficulties, show us your code.

Hi

Thanks for a reply. This is my scenario i am trying for
Initially i am looking to delete files from specific folder whenever limit is crossed by using shell script and when i am done with that i will try to do it on the email messages

Alright..
Great, Please, issue this command and give back the result.. tell us which part of your HDD you want to monitor.

Also, please tell if you want the react be taken looking at the over all percentage (Use %) or looking at the available capacity.

I'll try my best to help you :-)

Regards..

I got this output as below

Filesystem Size Used Avail Use% Mounted on
/dev/sda3 11G 7.8G 2.0G 81% /
/dev/sda2 11G 158M 9.5G 2% /home
/dev/sda1 1.1G 24M 936M 3% /boot
tmpfs 778M 0 778M 0% /dev/shm
/dev/md0 112M 5.8M 100M 6% /raid

i got a folder named oldfiles that is in my home directory so can monitor any part like /dev/sda3 by looking at the available capacity

You could probably use the "du -s $FOLDERNAME" command and check to see if a certain size has been reached then use the following find command:

find $FOLDERNAME -mtime $DAYS -exec rm -f {} \;

$FOLDERNAME is the full pathname to your folder and $DAYS would be how long ago the file was last modified.

So in a script you would just check the value returned from running `du -s $FOLDERNAME`. The return value is in kilobytes usually I think so keep that in mind. Then execute the find command if your condition returns true.

This should be a pretty simple script to implement.
