Installing RVM to /home/master/.rvm/
    Adding rvm PATH line to /home/master/.profile /home/master/.mkshrc /home/master/.bashrc /home/master/.zshrc.
    Adding rvm loading line to /home/master/.profile /home/master/.bash_profile /home/master/.zlogin.
Installation of RVM in /home/master/.rvm/ is almost complete:

  * To start using RVM you need to run `source /home/master/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM
