If I could add the UNLINK feature of File::Temp to this, I'd be set!

Just one thought.

If you've ever had a long download interrupted just before it completes, and then discovered that the link became immediately invalid as soon as the download was interrupted thus preventing you from just completing the partial download and forcing you to start the whole process over from scratch, you might consider your users and abandon that idea.

I remember having to restart a 400MB download from IBM, 8 times before it completed properly. Given I was using a 56kb modem and it always seemed to get to around the 350MB mark before aborting, it was intensely frustrating.

    I've been there, but a lot of the good anti-leech ... will let you resume with a new link, well using wget anyway (since it does its bytes/range getting based on filename/filesize, not url)

      Did you read the bit I quoted?

      I wasn't suggesting the OP should drop anti-leaching; just his notion to have the temporary file or link disappear as soon as the script ends.

[ambrus]: Corion: the solution depends on who for. Some non-math presentations need to show lots of graphics or photos, with fine details and color. For those, blackboard or overhead transparencies aren't so good (yes, you can print on transparencies, but there's s
