Retrieving streamed Flash video on Linux

This blog post on commandlinefu.com shows a fantastic one-liner to retrieve a streaming Flash file as it is being played. It seems that Flash writes to a file, but then deletes that file even as it is being used.

Reproduced here in case the other blog disappears one day:

for h in `find /proc/*/fd -ilname "/tmp/Flash*" 2>/dev/null`; do ln -s "$h" `readlink "$h" | cut -d' ' -f1`; done
