Deleteing archive files

Gops_1 — Wed, 27 Aug 2008 06:27:46 GMT

I have filled with lots archive files in the directory /u01/archives

It is increasing every day. But i need to write a bash/perl script and put it in crot tab. The logic is

To check the disk utilization of /u01/archives if it exceeds 80%, then delete the archive files.

Does anyone has this in your environment. How do you manage archive files ? Please share your automation in your env. plz...

Points Points....

Thanks

Hi Gops

You can add enrty in Cron which will find files on this FS which will clear/Zip the logs for some time old say 30 days

Entry in Cron

15 00 * * * /usr/bin/find /u01/archives -type f -mtime +30 -exec /usr/bin/compress {} \;
it will compress files

to delete tham

30 00 * * * /usr/bin/find /u01/archives -type f -mtime +90 -exec /usr/bin/rm {} \;

Sanjeev

Hi,

You can start with utilisation check

bdf /u01/archives |grep "80%"
if [$i==0]

find files to be deleted
remove files

Also provide cron requirements so that we can help you!!

Crontab syntax :-

A crontab file has five fields for specifying day , date and time followed by the command to be run at that interval.

* * * * * command to be executed
- - - - -
| | | | |
| | | | +----- day of week (0 - 6) (Sunday=0)
| | | +------- month (1 - 12)
| | +--------- day of month (1 - 31)
| +----------- hour (0 - 23)
+------------- min (0 - 59)

If you put on cron on a daily/hourly basis, this might help.

while bdf /u01/archives |grep '8[0-9]%'
do
ls $(ls -1rt /u01/archives/*|head -1)
exit
done

>ls $(ls -1rt /u01/archives/*|head -1)

-replace the first ls with rm to remove
-head -1 is taking the oldest file from the sorted by date list.
increase the number for the number of files you want to remove as per your requirement. You have to make the cron either hourly or daily/weekly as per your data growth.

Regards.

Delete all? Or only older ones until below X%?

>Sanjeev: 15 00 * * * /usr/bin/find /u01/archives -type f -mtime +30 -exec /usr/bin/compress {} \;

You can improve it by using gzip and skipping files that were gzipped:
find /u01/archives -type f ! name "*.gz" -mtime +30 -exec gzip {} +

And speed up the rm:
find /u01/archives -type f -mtime +90 -exec rm -f {} +

Checking if > 80%:
if [ $(bdf /u01/archives | awk '/% / {print $(NF-1)+0}') -gt 80 ]; then
echo "greater than 80"
fi
