The ls brace expansion is a powerful yet often overlooked feature of the ls command in Unix-like operating systems. This guide will delve into the intricacies of ls brace expansion, unlocking its full potential to enhance your file management workflow.
In ls brace expansion, curly braces {}
are used to specify a set of files or directories. The contents within the braces can be a combination of files, wildcards, and other special characters. This powerful feature allows you to perform intricate file selection operations with ease.
