Merge files in a directory
Hey Guys,

I want to merge all files (Apache Tomcat Access Logs) for a particular date say "Aug 24" to be merged into a single file.

Is there any quick hack for that ?
Code:
[tomcat@localhost logs]$ ls -alrth access_log2016-08-*|grep "Aug 24"
-rw-rw-r--. 1 tomcat        tomcat          16M Aug 24 00:00 access_log2016-08-23.23.log
-rw-rw-r--. 1 tomcat        tomcat         6.8M Aug 24 01:00 access_log2016-08-24.00.log
-rw-rw-r--. 1 tomcat        tomcat         4.7M Aug 24 02:00 access_log2016-08-24.01.log

-rw-rw-r--. 1 tomcat        tomcat          40M Aug 24 21:00 access_log2016-08-24.20.log
-rw-rw-r--. 1 tomcat        tomcat          37M Aug 24 22:00 access_log2016-08-24.21.log
-rw-rw-r--. 1 tomcat        tomcat          26M Aug 24 23:00 access_log2016-08-24.22.log
[tomcat@localhost logs]$

They should be merged into single file as per date time in ascending order so access_log2016-08-23.23.log then access_log2016-08-24.00.log so on and so forth.

We can do manually like cat individual file but want to explore more smarter way. I heard from my colleague a command called plus to concatenate into single file ,but not 100% sure..

Please assist.
