Fix Terminal error message "-bash: /etc/profile.d/rvm.sh: No such file or directory"
You should also look at /etc/profile file, as it may have references to /etc/profile.d/rvm.sh. 

It's also worth it to read the manual for bash, as it lists all files bash will look at for configuration. This will be towards the end of the man page. To read it, in Terminal.app type man bash.

Finally, you can run, again in Terminal.app, the following command: 

grep -R 'rvm.sh' /etc


This will look for all files inside /etc, recursively, that contain rvm.sh text in them.
