"It's always good to have a repeatable, known good method and/or procedure for doing things. You'll start to remember how to do these tasks and in the event something goes wrong, you'll have a standard documented set of steps to refer back to for troubleshooting."
Alternatively, you can always reference the Linux System Administration Handbook online at https://mog.dog/files/SP2019/2017%20Nemeth%20Evi%20etal%20-%20UNIX%20and%20Linux%20System%20Administration%20Handbook%5B5thED%5D_Rell.pdf Or pick up a paper copy and keep it on your desk. Highlight sections, use those colored tabs, write notes in the margins, etc. This book is highly recommended and often referenced by actual Linux Sys-Admins. It might be a bit of your head technically, but I found it easier to read and grok concepts than from just Linux technical manuals as they authors do a better job of explaining technical details, connecting concepts together so the reader gets a more complete picture.
