Description: The while loop in Bash is a control structure that allows executing a block of code repeatedly as long as a specified condition is true. This feature is fundamental in programming, as it enables automation of tasks and repetitive operations without the need to write the same code multiple times. The basic syntax of the while loop consists of the keyword ‘while’, followed by a condition in brackets, and a block of code that will execute as long as the condition remains true. This type of loop is particularly useful in situations where the number of iterations is not known in advance, allowing the program to continue running until an exit condition is met. While loops are widely used in shell scripts for tasks such as file manipulation, process management, and administrative task automation. Their flexibility and simplicity make them an essential tool for system administrators and developers working in various programming environments.
