问题
Is it possible while using the Ruby version manager to run scripts not from the console but using other ways — at system startup or by a keyboard shortcut for example?
回答1:
RVM installs a command rvm-shell. You can use rvm-shell, pass it whatever you would pass rvm use, then you can execute a shell command.
rvm-shell will set your environment for that shell script, or you can use rvm-shell on one line, and have it execute the parameter as a shell command.
For example:
rvm-shell rbx-2.0 -c 'which ruby'
Which should equal your rbx ruby.

It'd help to know the system, but the answer is yes, though you'd need to either know which is the current directory, or set the system ruby to be the one you needed for these scripts (especially startup). You might also need to experiment, as it would depend at which point in the startup you needed the scripts to run, but you can probably get more answers on that from the irc rvm channel.

rvm default do /path/to/ruby/script
