Copy all the lines to clipboard

Question

Is there any way to copy all lines from open file to clipboard in VI editor. I tried yG but it\'s not using clipboard to store those lines.

So

Answer 1

Well, all of these approaches are interesting, however as lazy programmer I use yank all line by using combination of number + y

for example you have source code file with total of 78 lines, you can do as below:

1. gg to get cursor at first line
2. insert 78 + y --> it yanks 78 lines below your cursor and current line
