undelete file that mplayer is still playing.
 

ok, I unrared a movie,started it in mplayer, it plays fine, then I deleted the rar files and accidentally the movie.avi file. mplayer is still playing the movie.
Question is how can I undelete the movie?

for posterity's sake and anyone else who might find themselves here.
First you need a goat, and a fire, and a stone table with the kernel source etched on its surface. chanting these commands.as you lead the goat into the fire...
#ps aux for the pid of mplayer
#lsof -p PID
and when the console breathes the filename of the movie you are playing it will also return the inode number of the deleted file
#sync
#debugfs /dev/deviceOfLostFile
#dump <inode_number> /another_filesystem/lostvid
#quit
Chase the flaming goat into the neighbors back yard while dancing arcane folk dances and screaming my name is Richard Stallman.

Ha, nice solution! Hope you do end up finding that goat...

I got the file back and the charred goat is hanging around the dumpsters at the local strip mall. It's the Penn Station Manager's problem now.
