What changes when you use this on Linux?
Equivalent task, different tool
Windows %USERNAME% maps to echo "$USER" 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.
For the broader concept behind this mapping, read Linux command-line basics.
