A question mark is used to mark predicates—methods that return a Boolean value. For example, the Array and Hash classes both define methods named empty? that test whether the data structure has any elements. An exclamation mark at the end of a method name is used to indicate that caution ...

根据文件注释内容可以发现,当前的可执行文件是RubyGems在安装Cocoapods的时候自动生成的,同时会将当前的执行文件放到系统的环境变量路径中,也即存放到了/usr/local/bin中了,这也就解释了为什么我们通过gem安装cocoapods之后,就立马能够识别pod可执行环境了。
(i.e. Array#empty?).[link] The names of potentially "dangerous" methods (i.e. methods that modify self or the arguments, exit!, etc.) should end with an exclamation mark. Bang methods should only exist if a non-bang method exists. (More on this.) [link] Name throwaway variables _...
