Tab is your friend! At least in zsh it manages file name completion well - including cycling through options of there is more than 1 match for your partial name. Of course, you could get more advanced with parameter tricks, eg. ${i%.ps}.pdf for changing the extension of $i from ps to pdf. (Technically: truncating the ending iff it matches ".ps" and adding ".pdf" no matter what.)
