vim：如何将 shell 命令“:!echo foo”的输出重定向到缓冲区？

Question

给定两个并排的缓冲区，源代码位于缓冲区 1 中，如何运行编译器（或任何命令行程序）并在缓冲区 2 中查看其输出 (

stdout

)？

另外，如何使用当前或指定的缓冲区作为此命令行程序的

stdin

？

Answer 1

您可以使用

:r! command

执行 shell 命令并将其输出读取到当前缓冲区。

Answer 2

如果你看

:h :b

：

:[N]b[uffer][!] [+cmd] [N]              :b :bu :buf :buffer E86
                Edit buffer [N] from the buffer list.  If [N] is not given,
                the current buffer remains being edited.  See :buffer-! for
                [!].  This will also edit a buffer that is not in the buffer
                list, without setting the 'buflisted' flag.
                Also see +cmd.

对于

+cmd

：

                                                        +cmd [+cmd]
The [+cmd] argument can be used to position the cursor in the newly opened
file, or execute any other command:
        +               Start at the last line.
        +{num}          Start at line {num}.
        +/{pat}         Start at first line containing {pat}.
        +{command}      Execute {command} after opening the new file.
                        {command} is any Ex command.

所以：

:2b +r!date

将打开缓冲区 2，并读取

date

命令的输出。
