 ====== Permissions for Directories ======
-\\
+<color darkorange>2016</color>
+----
 \\
 The same series of permissions may be used for directories but they have a slightly different behaviour.
 \\
-r - you have the ability to read the contents of the directory (ie do an ls)
+        r - you have the ability to read the contents of the directory (ie do an ls)
-w - you have the ability to write into the directory (ie create files and directories)
+        w - you have the ability to write into the directory (ie create files and directories)
-x - you have the ability to enter that directory (ie cd)
+        x - you have the ability to enter that directory (ie cd)
 \\
+Example:
+\\
+        ls testdir (list testdir contents)
+        file1  file2  file3
+        chmod 400 testdir (400 is 100000000) so r--- --- ---
+        cd testdir (change directory to testdir)
+        -bash: cd: testdir: Permission denied
+        chmod 100 stops access to a directory
+\\
+\\
+Example2:
+\\
+        chmod 100 testdir - (100 = 001000000 or --x --- --- so execute rights only)
+        ls testdir
+        ls: cannot open directory testdir: Permission denied
+        cd testdir - I can't list the director, but I can change to it
+        cat file1 - and I can view a file I know exists!
+        this is a test file
+        you have opened it
+\\
+\\
+I am sure I'll find a use for that? :)
