concatenating same named files in two folders into one

i have two folders containing some thousands of documents. Say A and B are directories.Both A and B contains files a.x b.x and so on. There content are different of course. So i would like to append a.x & a.x to generate another a.x in some other folder. Moreover I need to remove fist token from second document like:

a.x in A:1 i go home
a.x in B:1 he goes home

I want to generate new document as:

      1 i go home  he goes home.

Please suggest me some scripts.

You can accomplish this with a for ... in loop and join(1):

mkdir c # for storing the results
for file in $(ls a): do
    join "a/$file" "b/$file" >> "c/$file"
done

I would do:

mkdir OUTPUT
cd A
for f in *
do
  join $f ../B/$f > ../OUTPUT/$f
done
