====== Remove Directory ======
\\ 
\\ 
Odd as it sounds, I seem to have trouble removing directories, when I try:
\\ 
    rm directory
\\ 
I get the error:
\\ 
    rm: cannot remove ‘alan’: Is a directory
\\ 
If I do a **ls -a -l** to see the directory contents I get:
\\ 
    total 8
    drwxrwxr-x+ 2 pi pi 4096 Aug  1 21:58 .
    drwxrwxr-x+ 3 pi pi 4096 Aug  1 21:58 ..
\\ 
total 8 - 8 what??
\\ 
Anyway, this will remove a directory (and any files in it)
\\ 
    rm -r directory
\\ 
\\ 
You need to be 100% sure that there is nothing in the directory you need before you do this.
