Simplify Unix Path Simplify Unix Path

You can think about it as simplifying of the first argument "cd" command (a standart bash command). Simplifying means making shorter.

For instance if I do cd a/../b it works the same as cd b. Which means "b" is simplifying of "a/../b". It is much easier to explain everything using examples.
