长进程shell脚本cgi？

我有一个 CGI shell 脚本，用于下载软件包列表。它会打印有关该进程的一些信息，然后开始运行它。完成后，它会显示作业的结果。

它工作得很好，但是，在该过程完成之前，浏览器上不会显示任何内容。有没有某种方法可以告诉浏览器加载已有的信息并保持不变？

例如：

#!/bin/bash
echo -e "Content-type: text/html\n\n"

wgetCom="wget --quiet"

echo "<html><body><pre>"    

    echo    "Downloding autoconf"
    $wgetCom http://people.redhat.com/eblake/autoconf/autoconf-2.68.tar.bz2

    echo    "Downloding automake"
    $wgetCom http://ftp.gnu.org/gnu/automake/automake-1.11.1.tar.bz2

    echo    "Downloding bash"
    $wgetCom http://ftp.gnu.org/gnu/bash/bash-4.1.tar.gz

    echo    "Downloding binutils"
    $wgetCom http://ftp.gnu.org/gnu/binutils/binutils-2.20.1.tar.bz2

    echo "Download is Done"


echo "</pre></body></html>"

我需要的是在处理 shell 脚本时显示 echo。

任何帮助将不胜感激。

原文

I have a CGI shell script that download a list of packages. And it prints some information about the process and then starts running it. When complete, it shows the result of the job.

It works perfectly, however, on the browser doesn't show any thing until after the process is complete. Is there some way that tell the browser to load the information it already has and hold tight?

for example :

#!/bin/bash
echo -e "Content-type: text/html\n\n"

wgetCom="wget --quiet"

echo "<html><body><pre>"    

    echo    "Downloding autoconf"
    $wgetCom http://people.redhat.com/eblake/autoconf/autoconf-2.68.tar.bz2

    echo    "Downloding automake"
    $wgetCom http://ftp.gnu.org/gnu/automake/automake-1.11.1.tar.bz2

    echo    "Downloding bash"
    $wgetCom http://ftp.gnu.org/gnu/bash/bash-4.1.tar.gz

    echo    "Downloding binutils"
    $wgetCom http://ftp.gnu.org/gnu/binutils/binutils-2.20.1.tar.bz2

    echo "Download is Done"


echo "</pre></body></html>"

what i need is to show the echo's while process the shell script.

Any help would be much appreciated.

您要求的是关闭输出缓冲。我不确定 bash 是否会这样做或如何禁用它，但我确实知道如果 apache 配置为压缩输出，则它不会缓冲。添加包含以下内容的 .htaccess 文件：

BrowserMatch Mozilla no-gzip

看看它是否神奇地开始工作。如果没有，请回到绘图板。

What you're asking for is turning off output buffering. I'm not sure if bash does at all or how to disable it, but I do know that apache will not buffer if it is configured to compress the output. Add a .htaccess file with this content:
