在 Vim 中不使用临时文件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.

I want to be able to read man pages in Vim.

出于某种原因，Vim 似乎无法通过管道读取程序的输出.例如 (man ls) |vi 似乎不起作用，可以解释原因的人的奖励积分.

For some reason, it seems that Vim isn't able to read the output of programs through piping. E.g (man ls) | vi doesn't seem to work, bonus points for somebody who can explain why.

为了解决这个问题，我一直在使用以下小脚本:

To get around this, I've been using the following little script:

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

这个脚本使用临时文件，我认为它工作正常，但我想知道是否有一种好方法可以在 Vim 中阅读手册页而无需创建临时文件

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

推荐答案

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

根据man-page，你需要指定一个-的文件来让它从标准输入中读取；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)

它创建了一种伪文件并将其传递给 vi.

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