Comparing directories contents

[Man-Chicken]

Well, try this...

mkdir a
mkdir b
echo "a" >> a/a.txt
echo "b" >> b/a.txt
touch a/foo.txt

Then try `diff a b` and you'll get...
diff a/a.txt b/a.txt
1c1
< a
---
> b
Only in a: foo.txt

This is saying that In a.txt in both directories, the diff is that a/a.txt 
line 1 is "a" while line 1 in b/a.txt is "b", and alo that "foo.txt" only 
exists in "a".

If you then do...
mkdir a/foo
mkdir b/foo
echo "abc" >> a/foo/bar.txt
echo "123" >> b/foo/bar.txt
echo "123" >> b/foo/foo.txt

And then do `diff -r a b`, you'll get something like...
diff -r a/a.txt b/a.txt
1c1
< a
---
> b
diff -r a/foo/bar.txt b/foo/bar.txt
1c1
< abc
---
> 123
Only in b/foo: foo.txt
Only in a: foo.txt
