Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows netsh advfirewall firewall add rule maps to sudo for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Distribution details matter
The Debian/Ubuntu, Fedora and Arch rows are not identical. Use the row for your distribution instead of changing only the package-manager name in an example.
Elevated privilege appears in this workflow
At least one example uses sudo. Confirm the target path, device, service or package before running the elevated form; do not add sudo simply to bypass an unexplained permission error.
For the broader concept behind this mapping, read Linux permissions for Windows users.
