The main question - end of line Show $ goes to the end of line, remains in command mode A goes to the end of line, switches to insert mode Conversely - start of line (technically the first non-whitespace character) ^ goes to the start of line, remains in command mode I (uppercase i) goes to the start of line, switches to insert mode Further - start of line (technically the first column irrespective of whitespace) 0 (zero) goes to the start of line, remains in command mode 0i (zero followed by lowercase i) goes the start of line, switches to insert mode For those starting to learn vi, here is a good introduction to vi by listing side by side vi commands to typical Windows GUI Editor cursor movement and shortcut keys. vi editor for Windows users The default editor that comes with the UNIX operating system is called vi (visual editor).

Searching and Replacing in (ex Mode): vi also has powerful search and replace capabilities. The formal syntax for searching is: :s/string For example, suppose we want to search some text for the string “geeksforgeeks” Type the following and press ENTER: :s/geeksforgeeks Input: Output: finding the first match for “geeksforgeeks” in text will then be highlighted. The syntax for replacing one string with another string in the current line is: :s/pattern/replace/ Here “pattern” represents the old string and “replace” represents the new string. For example, to replace each occurrence of the word “geeks” in a line with “geeksforgeeks” type: :s/geeksforgeeks/gfg/ Input: Output: The syntax for replacing every occurrence of a string in the entire text is similar. The only difference is the addition of a “%” in front of the “s”: :%s/pattern/replace/ Thus repeating the previous example for the entire text instead of just for a single line would be: :%s/gfg/geeksforgeeks/ Reference: http://www.linfo.org/vi/ How do you go to the last line in vi mode?If you're already in vi, you can use the goto command.
