Rename files and directories recursively under ubuntu /bash

Question

I want to rename all files and directories that contain the word \"special\" to \"regular\". It should maintain case sensitivity so \"Special\" won\'t become \"regular\".

Answer 1

If you don't mind installing another tool, then you can use rnm:

rnm -rs '/special/regular/g' -dp -1 *

It will go through all directories/sub-directories (because of -dp -1) and replace special with regular in their names.
