D.5. Problems with Deletions
-
You've deleted the wrong text and you want to get it back.
-
There are several ways to recover deleted text.
If you've just deleted something and you realize you want it back,
simply type u to undo the last command (for example, a dd).
This works only if you haven't given any further commands, since
u only undoes the most recent command.
On the other hand,
a U will restore the line to its pristine state; the way it
was before any changes were applied to it.
You can still recover a recent deletion, however, by using the p
command, since vi saves the last nine deletions in nine numbered deletion
buffers.
If you know, for example, that the third deletion back is the one you want to
restore, type:
"3p
to "put" the contents of buffer number 3 on the line below the
cursor. This works only for a deleted line.
Words, or a portion of a line, are not saved in a buffer.
If you want to restore a deleted word or line fragment, and
u won't work, use the p
command by itself. This restores whatever you've last deleted.
