如何使用wget重命名下载的文件? [英] How to rename the downloaded file with wget?

问题描述

要从服务器下载SOFA统计信息，请使用wget命令:

To download the SOFA Statistics from the server I use the wget command:

wget -c http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp

在这种情况下，下载文件的文件名是download?source=files.如果我在命令中添加--output-document选项，以将输出文件重命名为sofastatistics-latest.deb，则dpkg软件包无法识别下载文件的格式.

The filename of downloaded file in this case is download?source=files. If I add the --output-document option to the command, to rename the output file to sofastatistics-latest.deb, the format of downloaded file is not recognized by dpkg package.

dpkg-deb: error: `sofastatistics-latest.deb' is not a debian format archive

使用提供的链接，下载的文件将始终是* .tar.gz.要使用真实名称获取它，只需添加--content-disposition选项(感谢@ 6EQUJ5！):

With the provided link the downloaded file always will be a *.tar.gz one. To get it with the real name just add the --content-disposition option as this (thanks to @6EQUJ5!):

wget --content-disposition http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp

但是我需要一个* .deb文件，所以这里是@creaktive，我不得不搜索* .deb文件链接.

But I needed a *.deb file, so here was right the @creaktive, I had to search for a *.deb file link.

感谢大家的回答！

推荐答案

将标准输出重定向到任意文件名始终有效.您按照 man wget 所说使用-O

A redirect of standard output into arbitrary file name always works. You are doing it correctly as man wget says, using -O

wget http://www.kernel.org/pub/linux/kernel/README -O foo

实际上，您必须在文件中获取HTML(通常可以通过 man文件进行检查).

Indeed, you must be getting an HTML in your file (usually can be checked with man file).

在您的情况下，客户端收到的是 302找到的(您可以使用 curl -v URL 进行检查).

In your case client is receiving 302 Found (you can check it with curl -v URL).

以下curl通过遵守3xx来达到目的:

The following curl does the trick by respecting the 3xx:

$ curl -L http://sourceforge.net/projects/sofastatistics/files/latest/download?source=files -o foo.deb

$ file foo.deb 
foo.deb: gzip compressed data, was "sofastats-1.3.1.tar", last modified: Thu Jan 10 00:30:44 2013, max compression

wget 应该有类似的选项来容忍HTTP重定向.

There should be similar option for wget to tolerate HTTP redirects.
