nd cached Flash player files

Some versions ago the Adobe Flash player stored cached files in /tmp/.
Actually the latest player sill stores the cached files in /var/tmp/ but uses a trick to hide them from the user:

The file is marked as deleted, but the file handler and data on disc still exist.
So what to do if you cached a video and want to save it for later use?

Look up the PID of "libflashplayer.so" (use "ps") and find files which are used by this process (using "lsof").
You will find something like "/tmp/Flash*".
This file does not exist in /tmp/ but we will find the file handler in "/proc/${PID}/fd/".
Just list the content (ls -la) and grep for "Flash".
You will find something like:

lrwx------ 1 blub blub 64 Aug 18 07:53 15 -> /tmp/FlashXXsJu3NC (deleted)

Now you can play the file with "mplayer /proc/${PID}/fd/15" or copy it with "cp /proc/${PID}/fd/15 ~/Desktop/myfile.flv".

This little script will do all the above for you and find any cached file by the Flashplayer
