Fix PHP short_open_tags (<?)

This shell script changes all PHP short open tags (<?) in a directory (recursive) to the complete PHP open tag (<?php). Tested only on OSX 10.6 (bash 3.2.48), be sure to check the current state of your working copy code before running this.

# Gets all the files that has PHP short_open_tags 
# in the currently directory (recursively)
for filename in `grep -r '<? ' . | grep -v '.git' | cut -d : -f 1 | sort | uniq` then
    # Changes all short_open_tags in the file to <?php
    sed 's/<\? /<\?php /g' $filename > /tmp/a && mv /tmp/a $filename
done
