Diff between files in different directories

Question

I have the follow directory structure

./goodboys/a.txt
./goodboys/b.txt
./badboys/a.txt.boy
./badboys/b.txt.boy

I am using zsh. I want to diff all *.txt in goodboys with *.txt.boy in badboys.

I am not looking for all possible diffs, I need diffs between ./goodboys/a.txt and ./badboys/a.txt.boy ./goodboys/b.txt and ./badboys/b.txt.boy

Thanks in advance.

Answer 1

Using bash this is waht you need, change it for zsh:

for i in $( ls ./goodboys ); do

diff ./goodboys/$i ./badboys/$i".boy"

done
