This lab focused on learning how to use the VI editor, which is a terminal‑based editor in Linux. I learned how to open a file in VI, edit text, and save my work. Honestly, I already knew most of these commands since they are the same ones I used when I was learning UNIX.

Some challenges I faced were forgetting to switch between insert mode and command mode, and remembering which commands work in each mode. I also struggled a bit with recalling the insert‑mode commands, so I relied heavily on my lecture notes.

Overall, this lab was interesting because I got to experiment with many different commands in insert mode.
