title: Add source to bash
body: <p>In my Debian server, all users run sh, but root runs bash;
  when i start a ssh connection, i log in with my personal account that does not have root privileges;
  i've installed rvm and I want to use it as root because using it from my personal user, it fails installing everything since the user does not have permissions to write where is neeeded; so everytime i need to type</p>
  
  <pre><code>source /usr/local/rvm/bin/rvm
  </code></pre>
  
  <p>before  being able to use rvm; to avoid typing source command everytime, in sh i know i can put the command in /etc/profile file; is there something similar for bash?</p>
  
  <p>I've tried to add "echo aaa" to /etc/profile, to see what happen;
  when i login as my personal user, i get the "aaa" output; but when i type su and login as root, nothing happens... I think that when i use "su" command and login as root, the /etc/profile is not read</p>
  
  <p>The same happens after installing by rvm a ruby release: I setup the default ruby version (as root) and then the ruby command is available for my personal user (but if i do "su" again and try to type "ruby -v" as root, i get "command not found"</p>
  
  <p>Another thing: after login  with my personal user, the rvm command is available; after typing "su", no more; if I add the source command to /etc/profile, once login is done with personal user, i can see a screen output from rvm (some kind of doc); the same happens after using the source command as root</p>
