It common to get a huge backlog of log files in any application. Worse is the case when the application has a batch interface too.  And there comes the need to delete the files which are older comes up. Or you might want to just copy/move the files to an archive folder for later reference.

Here are the unix commands for them :

Copy to archive folder

Consier your log folder is /apps/myapp/data/logs and your archive folder is /apps/myapp/archive/logs and you want to copy “files” and not directories which are 5 days old , then

find /apps/myapp/data/logs -type f -mtime +5 -name '*.log'- exec cp {} /apps/myapp/archive/logs \;

and/or if you want to delete the files which are 5 days old,

find /apps/myapp/data/logs -type f -mtime +5 -name '*.log' - exec rm -f {} \;
