# Change Ruby version for single command with rbenv

> You can switch Ruby version temporarily with rbenv local

You can switch Ruby version temporarily with *rbenv local*

But it'd need to be switched back after you're done. Specially for a single command it's kind of pain. In those cases, you can use *RBENV\_VERSION* env variable.

```
RBENV_VERSION=2.6.3 ruby -v
```

This might be useful in a shell script or so.
