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.

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 type 2p The deletion in buffer 2 is placed after the cursor. If you re not sure which buffer contains the deletion you want to restore you don t have to keep typing np over and over again. If you use the repeat command . with p after u it automatically increments the buffer number. As a result you can search through the numbered buffers as follows etc. to put the contents of each succeeding buffer in the file one after the other. Each time you type u the restored text is removed when you type a dot . the contents of the next buffer is restored to your file. Keep typing u and
