Can I compare more than two directories?

The diff command does not support comparing more than two directories directly in a single command. However, you can compare multiple pairs of directories by running separate diff commands for each pair.

For example, if you want to compare three directories, dir1, dir2, and dir3, you would run:

diff -r dir1 dir2
diff -r dir1 dir3
diff -r dir2 dir3

This way, you can analyze the differences between each pair of directories individually.
