Duplicate a whole line in Vim

2018-05-29 10:03:29

如何在Vim中以类似于在Eclipse中的IntelliJ IDEA / Resharper或Ctrl + Alt +↑/↓中的Ctrl + D的方式复制整行？

yy or Y to copy the line
or
dd to delete (cutting) the line

then

p to paste the copied or deleted text after the current line
or
P to paste the copied or deleted text before the current line

Normal mode: see other answers.

The Ex way:

:t. will duplicate the line,

:t 7 will copy it after line 7,

:,+t0 will copy current and next line at the beginning of the file ( ,+ is a synonym for the range .,.+1 ),

:1,t$ will copy lines from beginning till cursor position to the end ( 1, is a synonym for the range 1,. ).

If you need to move instead of copying, use :m instead of :t .

This can be really powerful if you combine it with :g or :v :

:v/foo/m$ will move all lines not matching the pattern “foo” to the end of the file.

:+,$g/^s*classs+i+/t. will copy all subsequent lines of the form class xxx right after the cursor.

Reference: :help range , :help :t , :help :g , :help :m and :help :v

YP或Yp或yyp 。
