strpos() in Ruby?

In PHP there's a useful strpos function that finds the position of first occurrence of a string. Is there a similar way to do this in Ruby?

Solution 
  • str.index(pattern)

    Use the index() method. This will return the index if found, otherwise return nil.

    Usage:

    ruby-1.9.2-p136 :036 > str = "Ruby is awesome"
 => "Ruby is awesome" 
ruby-1.9.2-p136 :037 > str.index("is awesome")
 => 5 
ruby-1.9.2-p136 :038 > str.index("testtest")
 => nil
