Cutting and pasting text in an editor is a basic requirement. This recipe describes the cut and paste functions of vi and vim.
Cutting text in vi/vim is achieved with the various delete commands which are summarized below:
dd Delete current line
D Delete from cursor to end of line
d$ Delete from cursor to end of line
d0 Delete from cursor to beginning of line
dw Delete from cursor to end of current word
db Delete from cursor to beginning of current word
These commands must be given in command mode in vi/vim, not insert mode. All of these commands can be preceded by a number that is interpreted as the number of operations to perform. For example, 5dd is interpreted as delete 5 lines.
When a deletion occurs, the text deleted is stored temporarily in a buffer. This buffer can be pasted into the document relative to the current cursor position using the p (lowercase p) paste after the current cursor position or P (upper case P) paste before the current cursor position commands.
Beware that some commands in vi/vim will empty the buffer. Cursor movement is safe, but since there is only one buffer that is used for both cut/copy/paste/undo/redo, any function that uses the buffer (insert, replace, etc.) will send your cut text to limbo.
