# Evaluating One-Off Commands
|
|
|
|
When I need to quickly test something out in Ruby, I will often reach for
|
|
`irb`. However, there is an even quicker way to send a line of code to
|
|
ruby for evaluation. Use the `ruby` binary with the `-e` flag followed
|
|
by your line of ruby. For instance,
|
|
|
|
```
|
|
$ ruby -e 'puts Class.ancestors'
|
|
[Class, Module, Object, Kernel, BasicObject]
|
|
```
