Shell script to Backup/Maintain and Purge Log Files in Linux

Shell script to Backup/Maintain and Purge Log Files in Linux

In this post, I am going to share a script to the daily backup log file and keep old ones for 7 days and then purge them. You can change based on requirements.

Script:

#!/bin/bash

v_date=`date +%F`

cd /u01/oracle/appldev/10.1.2/webcache/logs

cp -p access_log  access_log_${v_date}

cat /dev/null > access_log

cp -p event_log  event_log_${v_date}

cat /dev/null > event_log

find /u01/oracle/appldev/10.1.2/webcache/logs -type f -name "access_log_*" -mtime +7 -exec rm {} \;

find /u01/oracle/appldev/10.1.2/webcache/logs -type f -name "event_log_*" -mtime +7 -exec rm {} \;

cd /u01/oracle/appldev/10.1.2/j2ee/home/log/home_default_island_1

cp -p server.log  server.log_${v_date}

cat /dev/null > server.log

find /u01/oracle/appldev/10.1.2/j2ee/home/log/home_default_island_1 -type f -name "server.log_*" -mtime +7 -exec rm {} \;

Now I will schedule this in cron to run daily at 12:05 AM.

05 00 * * * /home/appldev/scripts/logs_purge_scripts.sh > /tmp/logs_purge_scripts.log > 2>&1
