Batch renaming of files (Mac OSX / *nix)

How to batch/bulk rename files with automatic sequence number? Try the following shell script from your terminal (OSX/*nix)

1. Create a new directory <newdir>
2. Run the following command (you can replace newdir with the your directory name and some_prefix with your prefix the same applicable for extension as well. My eg., rename only the png files of the directory (there were no other extensions available).

i=0; for x in *.png; do cp \"$x\" "newdir/some_prefix_$i.png"; i=$(($i+1)); done

Windows should have supported bash scripts natively. OSX is handy only because they inherited from unix.
