Comparing directories with rsync

Syntax

rsync trailing /

Remember the eccentricities of rsync trailing slash behavior:

rsync /path/to/dir1 /other/path/to/dir2

results in the directory /other/path/to/dir2/dir1 synchronizing with /path/to/dir1, while

rsync /path/to/dir1/ /other/path/to/dir2

makes /other/path/to/dir2 itself sync with /path/to/dir1. (A trailing / on the target directory makes no difference.) Here, we'll consistently use the second (trailing /) version to try to avoid confusion.

Options

Comparisons

Compare two directories and all their contents in the usual rsync way, by name, size, and modification time:

rsync -rltni dir1/ dir2/
