How to use exec and du command to find out size of files

Question

I'm trying to create a script with the find command to find all directories with the name " bin " within the " /usr/ " directory. I also want to know the size of each of these catalogues. How would I do this by using the -exec flag and du command?

This is what I've managed to scrape together so far:

find /usr/ -name "bin" -exec 

du bin

Answer 1

find /usr -type d -name "bin" -exec du {} \;

Answer 2

The following oneliner outputs the directories and their total file sizes. The -c argument produces the grand total of the files inside.

$ find /usr -type d -name bin -exec du -shc {} +;

104K    /usr/src/gcc/contrib/reghunt/bin
67M /usr/bin
8.4M    /usr/local/bin
75M total
