Rename files in subdirectories according to the directory name. Dirty - files with spaces does not work (grrrr)

rename-files-in-subdirs.sh

for i in $(ls -1); { echo $i; (cd $i; for ff in * ; { aa=$((aa+1)) ;  mv "$ff" ${i}-${aa}.jpg } )  }

file structure before:

---

$ find .
.
./a
./a/eroit
./a/ert
./b
./b/adsflkjadslfjadsf
./b/asdfasdf
./c
./c/3400
./c/4353
./d
./ef
./ef/asdfasdfsadfsadfsadfsaf
./ef/asdflkasdf
./ef/rreoijweroiuwerowueroiwueroiuwer
./rg
./rg/1
./rg/2323
./thn
./thn/bla
./thn/cvbx
./thn/qwe
./thn/sadfa

---

and after:

---

$ find .
.
./a
./a/a-1.jpg
./a/a-2.jpg
./b
./b/b-1.jpg
./b/b-2.jpg
./c
./c/c-1.jpg
./c/c-2.jpg
./d
./ef
./ef/ef-1.jpg
./ef/ef-2.jpg
./ef/ef-3.jpg
./rg
./rg/rg-1.jpg
./rg/rg-2.jpg
./thn
./thn/thn-1.jpg
./thn/thn-2.jpg
./thn/thn-3.jpg
./thn/thn-4.jpg
