What changes when you use this on Linux?
Equivalent task, different tool
Windows arp -s maps to sudo ip neigh add IP lladdr MAC dev IFACE 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.
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.
