I believe VI is what you do not need me to introduce more, this tool since the birth of Unix has been the standard editor under the terminal. Almost every Unix or Unix-like operating system provides VI. Vim is the abbreviation of VI improved, which has a great expansion compared with VI. The VI improved 6.3 is used here.

Can it be a letter, or can it be a number   ? P     Pastes the contents of register a before the cursor position. If it is a full line copied with yy,         paste it on top of the line where the cursor is located.
