title: RVM Command: source ~/.rvm/scripts/rvm
body: <p>I'm going through the rails by example tutorial series. I'm trying my best to find solutions prior to asking questions, so if I have missed anything I apologise. </p>
  
  <p>Every time I need to boot up RVM from the command line in terminal I need to punch a command so that RVM initialises: <code>source ~/.rvm/scripts/rvm</code></p>
  
  <p>Is this normal? It seems that I cant get the RVM commands to work unless I punch in this code prior. Note I only have to enter the command once, not every time I need to enter an RVM command. </p>
  
  <p>Many thanks for your help. </p>
