Also add:

• Commands for killing hung Rstudio Server sessions (which happens)
• Paths for the different R configurations files, e.g. Renviron.site, Rprofile.site (https://rviews.rstudio.com/2017/04/19/r-for-enterprise-understanding-r-s-startup/)
• Linux commands for troubleshooting general system issues/health, such as top/htop for ressource monitoring, df for disk space usage, etc.
