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
it works the same as
. Which means "b" is simplifying of "a/../b". It is much easier to explain everything using examples.
Input: String. Non-Empty valid unix path.
Output: String. Unix path.
# last slash is not important simplify_path('/a/') == '/a' # double slash can be united in one simplify_path('/a//b/c') == '/a/b/c' # double dot - go to previous folder simplify_path('dir/fol/../no') == 'dir/no' simplify_path('dir/fol/../../no') == 'no' # one dot means current dir simplify_path('/a/b/./ci') == '/a/b/ci' simplify_path('vi/..') == '.' simplify_path('./.') == '.' # you can't go deeper than root folder simplify_path('/for/../..') == '/' simplify_path('/for/../../no/..') == '/' # not all double-dots can be simplyfied in related path simplify_path('for/../..') == '..' simplify_path('../foo') == '../foo'
