It allows you to iterate over a list of words, the output of a command, or a sequence of numbers. Mastering control flow is essential for writing effective shell scripts, and few structures are as fundamental or powerful as the loop.
Shell Script Loop Optimization Guide: Boost Performance and Efficiency
Common applications include reading input line by line from a file, monitoring system resources, or waiting for a service to become available. By leveraging wildcards, you can easily loop through text files, log files, or backup archives without needing complex directory traversal logic.
Performance Considerations and Optimization. This approach is frequently used to parse configuration files or handle user input line by line, ensuring that memory usage remains efficient even with large inputs.
