如何在将手册页转储到文本文件时保留格式

Question

看起来这应该是一个非常简单的,但我无法弄清楚(显然).

当我打开终端窗口并运行例如命令时man ffmpeg,我在终端中看到的输出如下所示:

FFMPEG(1)                                                            FFMPEG(1)

NAME
       ffmpeg - ffmpeg video converter

SYNOPSIS
       ffmpeg [global_options] {[input_file_options] -i input_file} ...
       {[output_file_options] output_file} ...

DESCRIPTION
       ffmpeg is a very fast video and audio converter that can also grab from
       a live audio/video source. It can also convert between arbitrary sample
       rates and resize video on the fly with a high quality polyphase filter.

......这就是我期望的样子.但是,当我尝试使用命令man ffmpeg > man_ffmpeg.txt将该信息转储到文本文件中时,结果我看起来像这样:

FFMPEG(1)                                                            FFMPEG(1)

我想要做的就是将通常在终端内看到的内容转储到文本文件中,但显然我做错了.最好的方法是什么？

man输出有很多隐藏的退格字符.您看到的所有额外S和BS字符都是特殊字符.以下命令将清除这些:

man ffmpeg | col -b > man_ffmpeg.txt

现在您可以获得清晰的纯文本输出.

要获得手册页的纯文本版本,没有退格和下划线,请尝试

#man foo | col -b> foo.mantxt
