[SlugLUG] Removing an old drive and replicating it's data

[Eric Carter]

After I copied my data off my old drive and onto my new drive, I
figured I'd play around with ls and diff to make sure all the files
were present in the new directory.

So I did this:

cd oldDebian
sudo ls -RA > ../od.ls
cd ..
cd oldhome
sudo ls -RA > ../oh.ls
cd ..
diff oh.ls od.ls

The only output of diff was this:

22d21
< .qt
84550,84551d84548
< ./.qt:
<

And I was like ... WTF? What is this saying? In one directory there's
a hidden folder called qt? And in the other there's a hidden folder
called qt inside of the current folder? Whats with the ./. vs .
distinction?

I checked the two folders and I could cd into the .qt folder (nothing
inside it). But I couldn't cd into the ./.qt folder in the other
directory (no such directory)

Anybody know what diff is trying to tell me? Or maybe this is ls's fault?
