Learning the vi Editor, Sixth Edition

4.3. Making Use of Buffers

You have seen that while you are editing, your last deletion (d or x) or yank (y) is saved in a buffer (a place in stored memory). You can access the contents of that buffer and put the saved text back in your file with the put command (p or P).

The last nine deletions are stored by vi in numbered buffers. You can access any of these numbered buffers to restore any (or all) of the last nine deletions. (Small deletions, of only parts of lines, are not saved in numbered buffers, however. These deletions can only be recovered by using the p or P command immediately after you've made the deletion.)

vi also allows you to place yanks (copied text) in buffers identified by letters. You can fill up to 26 (a-z) buffers with yanked text and restore that text with a put command at any time in your editing session.

4.3.1. Recovering Deletions

Being able to delete large blocks of text at a single bound is all very well and good, but what if you mistakenly delete 53 lines that you need? There is a way to recover any of your past nine deletions, for they are saved in numbered buffers. The last delete is saved in buffer 1, the second-to-last in buffer 2, and so on.

To recover a deletion, type " (double quote), identify the buffered text by number, then give the put command. To recover your second-to-last deletion from buffer 2:

"2p

The deletion in buffer 2 is placed after the cursor.
