Summary
This concludes a closely related set of topics. Bash variables, conditionals, loops, and arrays are tools in Bash scripting for storing data, making decisions, repeating tasks, and handling lists of values, respectively.
The loop is the star of the show. Just like the cast of any show, they require a supporting cast. In the case of loops, they require variables to assign labels to data, conditionals to test equality, and arrays to store data. Together, they work as a team and make your Bash scripts much more powerful and flexible.
In the next chapter, you’ll learn about Bash regular expressions, a valuable skill that you’ll need to master to search and match text effectively.
