That's what backups do for you. If you have no backup, then, you don't have a backup...

The best you can do is stop using the disk immediately -- and I mean stop using it, no writing to it at all, if you can't shut off the machine then remount the filesystem read-only. Any write has a chance of overwriting part or all of the deleted file. Then figure out the right raw-data recovery tool for use on your system. Something like magicrescue may work depending on what your system is and what you deleted. I can't predict what your odds of retrieving it are.

If you deleted a whole tree and not just one file, if you get back anything at all you're likely to get back a disorganized mess of instead of a nicely organized tree.
