{{Admon/caution|Do Not Build or Install Software Except Via RPM (dnf/yum)|Do not build or install software as the root user (using <code>sudo</code>) except in RPM form using the <code>dnf</code> or <code>yum</code> commands. Building or installing software as root may overwrite system files and be very difficult to track down. It is OK to install software into your own directories (e.g., <code>~/bin</code> or <code>~/local</code>).}}

== Multiuser Access ==

Remember that these machines are multi-user systems. Use the <code>w</code> or <code>who</code> commands to see who else is using them; you can also try using the <code>write</code> command to communicate with another user if required.
