UNIX for Advanced & Expert Users

So I'm trying to search for the top 10 or 15 items under a directory by file type. I want to run a command on a directory and get something like the following:

Example of expected output.. .PDF: 100, .txt: 95, .word: 80..

What would be the best way of going about this? I've searched around and couldn't really find a specific method on exactly doing this.

Thanks,

how about this for the starters:

Code:

find . -type f -name '*.*' | awk -F. '{a[$NF]++} END {for (i in a) print FS i ": " a[i]}'

Exclude files that start with a dot like .profile:

Code:

find . -type f -name '?*.*' | awk -F. '{a[$NF]++} END {for (i in a) print FS i ": " a[i]}'

You can easily postprocess it with | sort -k2n
