title: The PATH variable is set to empty, how to fix it
body: <p>I was trying to <strong>set up a new environmental path</strong> in my server, but <strong>instead of using bash.basrc I used /etc/profile</strong>. After editing I tried to <strong>recompile the file using source</strong> profile and it gave an error <strong>not a valid identifier</strong>. Now When I run <strong>echo $PATH it shows nothing</strong>, none of my programs are running,and I cant even edit the file to check if there was any error any help would be appreciated.
