Centos – How to delete old log files

bashcentos

I'm trying to figure out how can I delete old log files, I'm using Centos 6.5 and in my /var/log I see these old log files

messages
messages-20150802
messages-20150802

also the same in the /var/log/httpd directory

access_log
access_log-20150802
access_log-20150809
access_log-20150816
access_log-20150823

I need to delete the older files that end with numeric values but keep the main once. what command could I use to do this.

Thanks in advanced

You can just use this commands:

rm -f messages-*
rm -f access_log-*

It will delete all old logs which starts with "messages-" and "access_log-"

This will return true if a variable is unset or set to the empty string ("").

if [ -z "${VAR}" ];

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)
