How to compare directories?

To compare directories in a Unix-like operating system, you can use the diff command with the -r option, which allows for recursive comparison of subdirectories. Here’s how to do it:

Basic Command:

diff -r dir1 dir2

Explanation:

diff: The command used to compare files and directories.
-r: This option tells diff to recursively compare any subdirectories found within dir1 and dir2.
dir1 and dir2: These are the paths to the directories you want to compare.

Example:

If you have two directories named dir1 and dir2, you would run:

diff -r dir1 dir2

Output:

The output will show:

Files that are unique to each directory.
Differences in files that exist in both directories.

Additional Options:

-q: Use this option to suppress detailed output and only report whether the directories differ.
```
diff -rq dir1 dir2
```
--brief: Similar to -q, it reports only whether files differ or are unique.
