I finnaly made things work. What I did was create a new directory called Dereck1. Changed directories "cd" to Dereck1, then:

cp ~/Dereck/* .

Went back to directory Dereck, rm -rf ./*
Then up one directory and rmdir Dereck

Never could make this work.
mkdir /Dereck1
mv Dereck /Dereck1

Kept getting message:
mv: cannot access Dereck1

Any clue what is wrong?

Looks like it should have worked from the command book, but it did not, beats me. Sure would have been easier.

Thanks for the help.
