在不使用临时文件的情况下在vim中读取手册页的方法是什么 [英] What is a way to read man pages in vim without using temporary files

问题描述

我希望能够在vim中阅读手册页.由于某种原因，似乎vim无法通过管道读取程序的输出(即'(man ls)| vi'似乎不起作用，向可以解释原因的人加分)，并获得为此，我一直在使用以下小脚本:

I want to be able to read man pages in vim. For some reason, it seems that vim isn't able to read the output of programs through piping (i.e '(man ls) | vi' doesn't seem to work, bonus points to somebody who can explain why), and to get around this, I've been using the following little script:

tempo = `mktemp`
man $1 > $tempo ; vi $tempo

该脚本使用临时文件，我认为它可以很好地工作，但是我想知道是否存在一种不使用临时文件来读取vim手册页的好方法

This script uses temporary files which I guess works fine, but I was wondering if there was a good way to read man pages in vim without resorting to making temporary files

推荐答案

由于某些原因，似乎vim无法通过管道[…]

For some reason, it seems that vim isn't able to read the output of programs through piping […]

根据手册页，您需要指定一个文件-以便从标准输入中读取该文件；所以:

According to the man-page, you need to specify a file of - to get it to read from standard input; so:

man ls | vi -

如果这不起作用，您可以尝试使用进程替换:

If that doesn't work, you might try using process substitution:

vi <(man $1)

创建一种伪文件并将其传递给vi.

which creates a sort of pseudo-file and passes it to vi.
