it could be worse, could have been 'rm *', as root

whatever you do, run it from a usb stick, so you have no interaction 
with the hard disk file system. i do not now which file system you are 
using, but a small number of blocks are kept somewhere for allocation 
(it used to be in the superblock, but who knows now). if you are unlucky 
the deleted blocks will get put in the cache of blocks to be used first.

another tool is called foremost again run from a usb.

if you have another computer create a usb rescue system to use.

let us know how you get on.

i can probably run a workshop on file recovery if people want. over 10 
years ago, i built a prototype tool to recover files from a hard disk 
using file entropy and heuristics, one of my MSc students built a better 
version. it is an interesting area.
