a bit of background. i have an image library, keywords for image \d+.jpg are stored in \d+.html, and this can be updated
Slight paradigm shift. Am not going to run this dynamically each time a keyword file is updated, but instead just update the keyword list. (troll through the keyword list, if seen, nothing, else appened new keyword to the end) keywords can only be added, not removed, should reduce load considerably.
Thanks to all that commented, it will definately help with the initial collection, and i'm a better perl programmer now too!
cheers
