Info

running vimtutor in the terminal that has some UNIX kernel will open up a tutorial on how to use the VI/VIM text editor
It's basically a text editor but on the terminal. Believe me that it's way way faster than just manually going through File Explorer or Finder

Syntax

vimtutor

There is a version on NeoVIM that will NOT be covered in CS 3377 Systems Programming in UNIX systems that can be accessed (assuming you have neoVIM)

nvim +Tutor

Remember that if VIM somehow doesn't work, VI might work because VIM is an improved version of VI.
The pipe operator, |, can work with VIM as well, opening, for example, file trees (assuming you have a recent Ubuntu installation, it should exist by default).
- The UTD cs1 server does have access to the tree command
- To look inside of a directory with tree, you need ONLY r or 4 permissions because you are displaying information about a directory. If you don't have permissions, it will give you an error message after the last field.

tree | vim -

/ means search in vim text editor, so it works like CTRL + F
