ruby on rails - How to split the file path of my head point gets changes? -

i want split file path according occurance of head point in file path.

case 1:

 puts fileutils.pwd()

output:

"/home/myhome/bigproject/now_with_bugs_fixed/subfolder/"

my project head bigproject. want split file path head point bigproject , want result as:

/bigproject/now_with_bugs_fixed/subfolder/

case 2:

 puts fileutils.pwd()

output:

"/home/data/cloud/vz-hadoop/bigproject/now_with_bugs_fixed/subfolder/"

now project head again bigprojectbut there little change in path.i want split file path head point bigproject , want result same in case 1:

/bigproject/now_with_bugs_fixed/subfolder/

i want in ruby language.please don't use index numbers.

 > s = fileutils.pwd  > s[s.index('/bigproject')..-1] => "/bigproject/now_with_bugs_fixed/subfolder/"

or split:

> s.split('myhome')[1] => "/bigproject/now_with_bugs_fixed/subfolder/"

(or ton of other ways.)

that said, sure want do?

if you're trying dig rails app's directory hierarchy, isn't approach i'd take, instead going along rails root directory path per comment.
