dunlike

dunlike is a command-line utility designed for comparing directories and reporting differences. It functions similarly to the standard diff command but operates on directory structures rather than individual files. The primary purpose of dunlike is to identify files that exist in one directory but not the other, files that have different content between the two directories, or files that are present in both but have different sizes or modification times.

The tool can be used to perform various comparison tasks, such as verifying the integrity of copied directory trees, identifying changes made to a configuration directory, or tracking the evolution of a project's file structure. dunlike typically offers options to control the level of detail in its output, allowing users to specify whether to compare file contents, only report differing file names, or include options for ignoring certain files or directories during the comparison.

Its output is usually presented in a clear, human-readable format, making it easy to understand which files are unique to each directory or which files have diverged. This makes dunlike a valuable tool for system administrators, developers, and anyone who needs to maintain and compare multiple directory hierarchies.
