Problem statement:
I have a number of directories, corresponding to series names, and random filename underneath each, as follows:
Title.S01E01/1234abc.mkv
Title.S01E02/5678def.mkv
Title.S01E03/10101qpr.mkv
....etc
Each directory is either empty or contains at most one file.
I need to rename files underneath each directory with the directory name, keeping the extension.
Research:
I tried the usual find/rename combination, but I couldn't exactly figure out the regex necessary to extract the directory name from the list of found files, and to appropriately pass it to the rename commend.
main-dir/sub-dir/file
)? Or is this depth the only depth that occurs?
