I am trying to set the $PATH permanantly for Vault. I have cd to etc and run sudo nano environment. This opens and I have appended my needed path onto the end like this: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/richb201/Vault"
And I save this to environment. I then open a new cli and type echo $PATH but the new path "/home/richb201/Vault" doesn't appear. What am I doing wrong?
