bash: wget 在循环中，奇怪的地址

Question

我写了一个小 bash 脚本，它根据插件名称列表从 wordpress 插件目录下载插件。它有效，但似乎 wget 被调用的次数比使用奇怪参数所需的次数多。

#!/bin/bash

pluginlist="list" #plugin list, line by line

outputdir="output"

urlprefix="http://downloads.wordpress.org/plugin"

ua="Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20070802 SeaMonkey/1.1.4"

if [ ! -f "$pluginlist" ]; then 

    echo List \file "$pluginlist" does not exist\!; 
    exit
fi

while read plugin_name; do

    wget -U $ua -O $outputdir/$plugin_name."zip" $urlprefix/$plugin_name."zip"

done <$pluginlist

echo \done

示例输出：

所以它在得到正确的地址之前得到了很多奇怪的地址。我不知道为什么会这样。

Answer 1

您需要引用您的用户代理字符串：

wget -U "$ua" -O $outputdir/$plugin_name."zip" $urlprefix/$plugin_name."zip"

否则，bash 会将其拆分为空格并将其作为多个参数传递给 wget...它试图将其视为 URL。

bash: wget 在循环中，奇怪的地址

bash: wget in a loop, strange addresses

bash

wget
