Nano is nearly ubiquitous making it great for these small edits, and it was easy to pick up as it has the common key combos listed at the bottom of the screen. When I was learning Linux this made things smoother than they could have been with other CLI editors. Vi took me a while to get used to and I had to look up commands, but I still install nano when I need it.

I get lost when working on centos.

-bash: nano: command not found

-bash: apt: command not found

~OS swap was highly effective, sysadmin is confused~

(Yes this is a joke)
