I don't know what goback does, but judging from the thread, I'd guess
it's a program to restore deleted items. Well, let me explain
something about direct access to thhe file system.
When you use the finder to delete something, it goes into the trash.
So, if you didn't want it deleted, you can move it out of the trash
again. Windows does the same thing with their recycle bin.
Most graphical operating systems do this.
Now, let's say you're at a dos prompt in windows.
del c:\windows\command.com will very happily remove the command.com
file for you. No recycle bin, and no undelete.
Ok, now on mac.
in terminal
as root.
rm _R /*
bye-bye drive contents. No recovery and no second changes.
And thus, the caution about being very careful when you're logged in
as root.
You can do pretty much the same thing in dos, but it takes a deltree
instead of just a del.
