Changing file names

I have file names as shown and want to change the name to have only the first four numbers.

Code:
/home/chrisd/Desktop/nips/nips_2013/5212-learning-feature-selection-dependencies-in-multi-task-learning.pdf
/home/chrisd/Desktop/nips/nips_2013/5213-parametric-task-learning.pdf

There are many examples of this. Try:
Code:
dir=/home/chrisd/Desktop/nips/nips_2013
cd "$dir"
for f in *.pdf
do
  if [ -f "$f" ]; then
    mv -- "$f" "${f%%-*}"
  fi
done

Are you sure that the first four number are unique? You could lose data if not:-
Code:
mv 1234-fileA 1234
mv 1234-fileB 1234

..... and fileA is lost.
