Question

I got a folder (lets say it’s name is ../TEMPO) with many folders inside [A,B,C..Z] on a linux machine.
Each folder has 3 more levels of folders. Some of the deeper folders are with lowercase name, Example:

A/F/m/O
Z/t/q/S

In the 4th level there are files which i would like to keep with the same name as it is now.

How can I rename just the folders name to uppercase recursively without changing the files name exists in a specific folder (../TEMPO)?

Verify the output of this command

find path/to/dir -type d | awk -F"/" '$NF != toupper($NF) {l = n = $0; sub($NF "$", toupper($NF), n); print "mv " l " " n;}' | tac

and if it looks fine, execute the results by piping the results to sh

find path/to/dir -type d | awk -F"/" '$NF != toupper($NF) {l = n = $0; sub($NF "$", toupper($NF), n); print "mv " l " " n;}' | tac | sh
