In Linux shell scripting, the continue command can be used in loops. For example, compared to the break command, when using continue , the loop skips the current iteration. Consider the following loop example (not shown in the text but for illustration):

        continue
    fi

2. Working with Functions

Functions in shell scripts are useful when you need to reuse the same block of
