What changes when you use this on Linux?
Same name, different environment
The basic command name umask is familiar on both platforms, but Linux path rules, quoting, permissions and available options can still change the result.
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 permissions for Windows users.
