我在我的 Windows 10 机器中使用 Linux shell (Ubuntu 20.04)。我有一个 bash 脚本应该

浏览一个包含 IP 列表的 .txt 文件

使用站点 curl 每个 IP https://ipinfo.io/用于修改后的 curl 输出

#!/bin/bash  
input="/mnt/d/Docs/BR Resources/iplist.txt"  
while IFS= read -r line  
do   
 curl https://ipinfo.io/$line  
done < "$input"

循环中每个 IP 的预期输出为:

{ "ip": "xx.xx.xx.xx",
"hostname": "c0241.brsol.com",
"city": "Ashburn",
"region": "Virginia",
"country": "US",
"loc": "xx.xxxx,xx.xxxx","org": "BR, Inc.",
"postal": "xxxxx",
"timezone": "America/New_York",
"readme": "https://ipinfo.io/missingauth" }

但是，我得到的输出是这个错误:

curl: (3) URL using bad/illegal format or missing URL

iplist.txt 的示例摘录

36.13.6.167
252.125.137.71
204.50.68.40
136.122.209.112
203.47.25.30
223.96.93.56
64.137.82.169
11.183.223.40
199.169.87.25
119.198.39.119

问题似乎是 $line 的值没有与 curl 命令的其余部分一起传递 .
如何解决此问题以获取此 .txt 文件中每个 IP 的修改后的 Curl 输出？

Answer 1

我在生成输出的 Windows 机器上执行了以下步骤:
将文件转换为 dos2unix.exe ./test.sh测试.sh:

# !/usr/bin/bash
input="iplist.txt"  
while IFS= read -r line  
do   
 curl https://ipinfo.io/$line  
done < "$input"

输出收到:
