Vim Command to Select All

This is a compact and powerful command. We're telling vim to yank the entire file from the first line to the last.
One & Done
:%y
yank every line in the file
Parting Thoughts
%
is an interesting operator in command-line-mode. It is equivalent to 1,$
(the entire file). So, we’re really just
passing a range to the yank operator. This shows us how easy it would be to yank any lines without a file.
