Feel proud that you have your "I can read" badge for shell scripting. We have developed our scripts to be interactive and prompting users for input during the script execution. These prompts can be used to simplify user operations on the command line. In this way, they do not need to remember the command line options or have passwords that end up stored in the command line history. When using passwords, we can silently store the value using the
read -sp options.
In the next chapter, we will take our time to look at the conditional statements in bash.
