I ran across a server in which all the inodes were used and this was causing myriad issues on the server.

# df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/sda5            16318464 16318464       0  100% /

I needed to find out where all the files were so my colleague Kale provided me with this little script to do what I needed.

for d in *; do echo -n "$d: "; find $d -type f | wc -l; done

This is not recursive so you'll have to drill down through the directories to find the root source.
