Recently I needed to search the server and find all error_log files, but I needed to also list the size of each file that was found - the purpose of this was to find users with unnatually large error logs so that I oculd tweak the error_reporting settings on each system.
I managed to find a very fast, very useful solution. The below searches all directories in /home/ for error_log and displays a list of all found files with the filesize first (in KB) followed by the files path.
find /home/ -name 'error_log' -printf "%p %k KB\n"
But of course you can also search with wildcards, with the find command I can also find all .log files for instance.
find /home/ -name '*.log' -printf "%p %k KB\n"
