man 2 undelete

Basically, a delete/rm command doesn't physically erase data from the
disk, it only removes the file entry. The data may still be there if
you're lucky.  I don't know what the issues are with ufs, however.
With an msdos filesystem it's pretty straightforward to get the data
back if that hard disk space hasn't been written over in the meantime.

But it helps...
