$ rbenv global xxx
Specify the version of ruby to use throughout the system. But in fact, it is a command only to write out ~/.rbenv/version file.
$ rbenv global 2.2.0 # => ~/.rbenv/version に 2.2.0 と書き出される
So even if you create or delete ~/.rbenv/version in other ways. The ruby version changes.
$ rbenv local xxx
Specify the ruby version to use for each project. But in fact, the command only writes the .ruby-version file to the current directory.
$ rbenv global 2.3.0 # => ./.ruby-version に 2.3.0 と書き出される
So even if you create or delete .ruby-version in other ways. The ruby version changes.
Behavior of rbenv
As mentioned earlier, rbenv global / rbenv local only rbenv global / rbenv local files. In fact, the behavior of rbenv determines the version of ruby.
order
rbenv first looks at the .ruby-version current directory. If there is, use it.
If not, look at the .ruby-version in the .ruby-version directory. If there is, use it. Repeat this until you reach your home directory ~/ .
If you go to your home directory but don't have .ruby-version , look at ~/rbenv/version . If there is, use it.
That is, if you create .ruby-version in .ruby-version home directory, global will not be referenced from anywhere.
environment
