Recursivly rename folders removing characters as required

HI guys here's hoping some on pout the can help

I have a large library of epub and mobi file creates some what by calibre.

Output of tree listing below

I would like to recursively rename the directories removing the brackets and numbers

I have been scratching my head over this one all day so any help would be gratefully appreciated

Any attempts beyond scatching your head?

yeah although i got a few splinters from the scratching

I can accomplish this fine with a line of text ie

give me the output i would like to rename to but how to apply this recursively to all directories is currently evading me

Try

find . -type d -name "*([0-9]*)" | while read FN; do echo mv $FN ${FN%([0-9]*)}; done

This doesn't check for three digits but allows for anything after the first digit; this may need some refinement. If the results comes close to what you need, remove the echo for real action.

Thanks for the heads up had to add some inverted commas due to spaces in the names so

worked a treat
