I was writing some instructions on how to install something (TeX-related - if you don't ask, I won't ruin your day by supplying more details) and used sudo to install system-wide. Someone commented that they didn't think that sudo was available on all Linux (or Unix) distributions.Are there Unix distributions that don't have sudo, and if so what are they? Is there a universally acknowledged Get me superuser privileges command that is on all systems?
How universal is sudo?
