How can I count the different file types within a folder using linux terminal?

Question

Hey I'm star struck on how to count the different amounts of file types / extensions recursively in a folder. I also need to print them to a .txt file.

For example I have 10 txt's 20 .docx files mixed up in multiple folders.

Help me !

Answer 1

find ./ -type f |awk -F . '{print $NF}' | sort | awk '{count[$1]++}END{for(j in count) print j,"("count[j]" occurences)"}'

Gets all filenames with find, then uses awk to get the extension, then uses awk again to count the occurences
