yes I know I could do this:

cat /proc/####/fd/32 > /dir/to/new/file.ext

but then all changes made by the process afterwards are not in the copy.

Of course there is a process still running and works with a file discriptor to the deleted file.

Onother question:
Is the space of the file on the underlying block device already marked as free? Or does this happen after all processes have closed all file descriptors pointing to the file?

I really want to undo the deletion. (get a link/name connected to the root inode of the file again)
Is there a way to do this?

Thanks
Lars
