如何在vim中运行指定的命令？

Question

我知道如何在vim中运行shell命令，在命令模式下输入

:!shell_command

现在，我在Vim打开的文件的第16行有一个命令。

cp /home/debian/Downloads/rar/rar /usr/local/bin

如何在vim中运行此命令而不键入所有命令？

当我点击:!打开ex命令行然后使用<C-r>"时，我明白了：

ls /tmp^m

我必须用退格键擦除^m，然后按回车键，是吗？ 我不能让^ M出现吗？

要在光标所在的行上运行该命令，可以将该行拉入剪贴板。键入:!以打开ex命令行，然后使用<C-r>"将命令粘贴到命令行。

所以将光标放在线型上并点击回车。

yy:!<C-r>"

看看:h <c-r>。

CTRL-R {0-9a-z"%#:-=.}                  *c_CTRL-R* *c_<C-R>*
        Insert the contents of a numbered or named register.  Between
        typing CTRL-R and the second character '"' will be displayed
        to indicate that you are expected to enter the name of a
        register.
        The text is inserted as if you typed it, but mappings and
        abbreviations are not used.  Command-line completion through
        'wildchar' is not triggered though.  And characters that end
        the command line are inserted literally (<Esc>, <CR>, <NL>,
        <C-C>).  A <BS> or CTRL-W could still end the command line
        though, and remaining characters will then be interpreted in
        another mode, which might not be what you intended.
        Special registers
