sudo: cd: command not found

Ever tried this:



Weird isn't it ?
I checked the "/etc/sudoers" and everything looked normal:

toamitkumar   ALL = (ALL) NOPASSWD: ALL

I have sudo access - which means I have access to everything (thats what my understanding was)
Well, I was wrong.

After thinking for a while I felt - 'cd' is not a program, it is built-in for bash shell. So, I had to do:

sudo -s or sudo su or sudo bash

and then 'cd'.

But be careful, that will open a shell for 'root' user.

require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')

And the other way (in my new files):

require 'spec_helper'

Synching them fixed it :))
