Equivalent task, different tool
Windows robocopy /xo maps to rsync -au source/ destination/ for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Portable across the compared distros
The Debian/Ubuntu, Fedora and Arch rows use the same command in this mapping. Package availability or defaults can still vary, so check the installed tool version when an option behaves differently.
