Rename
Rename is a command-line utility or tool used to batch rename files and directories by applying patterns, regular expressions, or simple text replacements. It is commonly available on Unix-like systems (e.g., Linux, macOS) as part of the Perl distribution or as standalone scripts, and it helps automate the tedious process of renaming multiple files at once. The tool supports complex transformations, making it valuable for organizing files, standardizing naming conventions, or processing data in bulk.
Developers should learn and use Rename when they need to efficiently manage large sets of files, such as during data preprocessing, log file organization, or project restructuring. It is particularly useful in scripting and automation workflows where manual renaming would be time-consuming and error-prone, such as renaming image sequences, cleaning up downloaded files, or adapting file names for compatibility with other tools.
