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.

  * 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.

  * To start using rails you need to run `rails new `.

 6. 卸载RVM

master@master:~$ rvm implode
Are you SURE you wish for rvm to implode?
This will recursively remove /home/master/.rvm and other rvm traces?
(anything other than 'yes' will cancel) > yes
Removing rvm-shipped binaries (rvm-prompt, rvm, rvm-sudo rvm-shell and rvm-auto-ruby)
Removing rvm wrappers in /home/master/.rvm/bin
Hai! Removing /home/master/.rvm
/home/master/.rvm has been removed.

Note you may need to manually remove /etc/rvmrc and ~/.rvmrc if they exist still.
Please check all .bashrc .bash_profile .profile and .zshrc for RVM source lines and delete or comment out if this was a Per-User installation.
Also make sure to remove `rvm` group if this was a system installation.
Finally it might help to relogin / restart if you want to have fresh environment (like for installing RVM again).

master@master:~$ rm /etc/rvmrc ~/.rvmrc
rm: cannot remove '/etc/rvmrc': No such file or directory
rm: cannot remove '/home/master/.rvmrc': No such file or directory
