How can we compare the contents of two folders using the diff command in Linux?

In Linux, the diff command can be used to compare the contents of two folders. The basic syntax for comparing the contents of two folders is as follows:

diff -rq <文件夹1> <文件夹2>

The -r option implies comparing subdirectories and files recursively, while the -q option only displays differences without showing specific content.

Example: I can’t wait to see the new movie that just came out.

diff -rq /path/to/folder1 /path/to/folder2

This command recursively compares the contents of folders folder1 and folder2, and displays the differences. If no output is shown, it means the contents of the two folders are identical.
