The answer is 42
dirname of 'a/b/c def a.b.c a.b/c a a.a .gitignore a a.a' is 'a/b . . a.b . . . . .'
basename of 'a/b/c def a.b.c a.b/c a a.a .gitignore a a.a' is 'c def a.b.c c a a.a .gitignore a a.a'
suffix of 'a/b/c def a.b.c a.b/c a a.a .gitignore a a.a' is 'c b/c a gitignore a'
root of 'a/b/c def a.b.c a.b/c a a.a .gitignore a a.a' is 'a/b/c def a.b a a a  a a'
