How can I undelete a file or directory?

[Thomas Ward]

I guess it comes down to how bad you want the files. You see If you remove a
file under any Unix system it assumes you want to completely remove that
file and it does.
Of course, X has trashcan/recycle bin like utilities, but in this case they
won't help you because you weren't using X when you removed the files.
One of the many bad habbits Windblows has taught people is that you can
delete any file you want and the recycle bin will almost always restore
it.Which means in the long run you never really deleted it because it eats
up space in a hidden folder on your hard drive.
