find find

In a recently performance analysis, I need to find out how many files in each of the directories/sub-directories to determine whether there is any heavily populated files in any of the directory.

What I need is to run find within find. Also I need to make sure the find will not traverse into any of the sub-directory. In Linux, you can specific "-maxdepth 1" to limit your depth.

First I need to write a script to find the number of files (no directory) in a given directory.

$ cat /tmp/find_f.sh
#! /bin/sh

n=`find $1 -maxdepth 1 -type f | awk 'END{print NR}'`
echo $1 - $n

Once that is done, I will have to run the above script for every directories/sub-directories. To find out the most populated directory, I simply pipe that to "sort" with -n for numeric sort.

$ find /usr/include -type d -exec /tmp/find_f.sh {} \; | sort -n -k 3 | tail
