To achieve a recursive loop through directories, we will use bash loops, specifically, a for a loop. The for loop is a common type of loop in Bash and other programming languages. It iterates over a given list

The script uses a for loop to iterate over a range of numbers from 1 to 20. The loop variable 'i' represents each number in the range. Within the loop, an if statement checks if the current number ('i') is odd using the condition i % 2 != 0. If the condition evaluates to ...
Finally, we will use the echo command for the loop to run through the directories. Technically, to perform the task, first we have to initialize a variable then we assign the dataset to the variable that we want to loop through. In our case, it cycles through the directories using the ...
