Lecture 03. Editors (Vim)

Complete vimtutor. Note: it looks best in a 80x24 (80 columns by 24 lines) terminal window.

It is a tutorial for beginners of vim. I will just put some notes which are not mentioned in course here.

• U command: When we press u in normal mode, we can undo the last command. What U does is fixing a whole line.

• Ctrl + G: show your location in the file and the file status. Type the linenumber you want to go, then press G, then you are there.

Lecture 01. Shell
