Whenever i type ‘echo $PATH’
only ever got back my old PATH – which i found impossible to change
Until now!
I created a .Profile file in my root directory (Mac:)
I copied my text edited file **
Now my echo $PATH reads perfect when I ask Terminal

My questions are:
1.If you don’t have a .profile file in the correct place – what are the possible locations that terminal reads and writes to when you type in ‘echo $PATH’ and sudo vi .bash_login (to edit this path)
OR what file is it reading to show you your $PATH!!! (because i was not able to change a file which reflected a change in $PATH in terminal

2.What is the root directory? is it MAC: or MAC/users/myname/

Now i have .profile files everywhere!!!
I just have big problems understanding what Terminal is editing and showing when you edit the $PATH via the sudo vi .bash_login OR sudo vi .bash_profile (my files were never showing a universally similar PATH)
