Script for deleting old log files in system

[Former Member]

Hi,

     This is Deepesh I am trying find some script to delete log files in \var\log\applog\nmon . We usually get this alerts that the file system is almost full and all we do is go to the path and delete old log files. So basically what i am looking for is the script that i can schedule in corn job . This script should keep logs for two months and delete the rest .

Hello Deepesh,

You can create a simple unix script using 'find' command.  Update the directory name where you want to delete the files.  I would suggest to test it before u implement it across the systems

Unix Script:

#!/bin/bash

find <directory> -mtime +60 -type f -exec rm {} \;

Hi Mudasir;

There two files named .profile and .sh_history apart from that any file older than that should be deleted .

Hello

I believe those are nmon files with extension .nmon

In that case you can create a script like this:

find . -xdev -type f -mtime +60 -name "*.nmon" -exec rm {} \;

To be sure that it is deleting the correct files list the files first using this:

find . -xdev -type f -mtime +60 -name "*.nmon" -exec ls -ltr {} \;

Hi,

I finally did this

#!/bin/sh

###

### Static variables

###

nmon_dir="/var/log/applog/nmon "

cd $nmon_dir

find $nmon_dir -xdev -type f -mtime +120 -name "*.nmon*" -exec rm {} \;

find $nmon_dir -xdev -type f -mtime +5 -name "*.nmon" -exec gzip {} \;

But I am not sure whether that .gz file will be stored .

[Reagan]

Hello

cd $nmon_dir

There is no need to specify cd $nmon_dir in the script as the find command is using the path $nmon_dir which is already defined as a shell varibale.

But I am not sure whether that .gz file will be stored

The files will be zipped in the location where they are present unless you specify another location.

Good Luck

Hello

nmon_dir="/var/log/applog/nmon"

Modify the script like this:

nmon_dir=/var/log/applog/nmon

Also try to list the files before deleting or zipping them.

Good Luck

Hi,

Firstly which logs are you referring to?

ABAP/JAVA/ AUDIT logs?

Be careful what you delete bu something similar to Mudasir's suggestion can work.

If your reasoning is for space you can use similar command and add

find <directory> -mtime +60 -type f -exec gzip -9{} \;

So insteaf of removing it zips them
