Hello Friends,

This is a basic find command that I modified a bit to show the size of the file it finds.

This is extremely helpful when trying to locate files that are taking up large quantities of space. e.g. apache log files, mysql logfiles.

This will show files in / that are larger than 20MB in / partition.

Code:

[root@badassweb1 ~]# find /root -type f -size +20000k -exec ls -lh {} \; | awk '{print $9 ": " $5}'
/root/mysqldb.sql: 125M
/root/blit.sql: 58M

You can also change the command to look in other places, change the value in red to any partition on your server. Lets say apache logs for this one.

Code:

[root@badassweb1 ~]# find /usr/local/apache/logs  -type f -size +20000k -exec ls -lh {} \; | awk '{print $9 ": " $5}'
/usr/local/apache/logs/wvmagic/access_log: 58M
/usr/local/apache/logs/933therazor/access_log: 53M
/usr/local/apache/logs/wrnn/access_log: 43M
/usr/local/apache/logs/tampabaysq105/access_log: 30M
/usr/local/apache/logs/thewendywilliamsexperience/access_log: 72M

Notice that the awk piece prints that size as well. This is what was helpful to me.

Hope this helps,

Jaysunn

Code:

find /usr/local/apache/logs  -type f -size +20000k -exec ls -lh {} \; | awk '{print $9 ": " $5}'

I run and I see very large files (my path is /corpwww/logs). Each file is 5 or 6gb. can I remove them?

By the way your location is set to 41.332032,-73.089775?? Is it google map location or just some random stuff fro /dev/random

?

What's Up Raj,
That location is for real. Derby CT, United States.

As for the logs.

Apache access_logs are used to show the access hits from the external users IP as well as other information. If you are not using those logs for gathering stat data then feel free to remove them. Perform a graceful restart of apache and it will recreate them at 0.

As for the apache error_logs, if you are not using those to gather data. They also can be removed. They will also get recreated when running a apache graceful restart.

Code:

$/usr/local/apache/bin/apachectl graceful

Also have a look at logrotate. This will help you keep your apache log files in check.

On redhat, the file is

Code:

/etc/logrotate.conf
