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]
