为什么我在Bash中的wget导致400 Bad Request错误？

Question

我在文本文件中有此数据：

  

-O BNU-ESM-pr-Historical-19560101-19601231.nc https://dataserver.nccs.nasa.gov/thredds/ncss/bypass/NEX-GDDP/bcsd/historical/r1i1p1/pr/BNU-ESM.ncml?var=pr&north=55&west=72&east=136&south=16&horizStride=1&time_start=1956-01-01T12%3A00%3A00Z&time_end=1960-12-31T12%3A00%3A00Z&timeStride=1

我正在将以下代码用于.sh文件：

#!/bin/bash
while read -r line; do wget $line; done < pr_china.txt

BASH中命令的结果：

ahmad@ahmad:/mnt/c/script_sh_files$ ./pr_china.sh

Answer 1

在使用pr_china.txt文件之前运行dos2unix。
