Shell string processing capabilities were weak, but recently in bash 4. In many scenarios, developers use structs as an efficient way to pass values, such as a return object from a method, or a basic data structure that would be used across the application. There are three main benefits to using a struct over a class: Structs are value types, and a copy of the data is created when you pass them into functions. Instead, we could parse the string and return a nullable int where the null value indicates that the input string was not a valid integer. If you are using a char, unsigned char, or byte array there is a way to accomplish the copy without knowing the length of the data. The class String includes methods for examining individual characters, comparing strings, searching strings, extracting parts of strings, and for converting an entire string uppercase and lowercase.
