sed - Bash command to remove leading zeros from all file names -

-

i have directory bunch of files names like:

001234.jpg 001235.jpg 004729342.jpg

i want remove leading zeros file names, i'd left with:

1234.jpg 1235.jpg 4729342.jpg

i've been trying different configurations of sed, can't find proper syntax. there easy way list files in directory, pipe through sed, , either move or copy them new file name without leading zeros?

for file in `ls`; mv $file `echo $file | sed -e 's:^0*::'`; done
