无法使用 wget 下载文件

Question

我无法使用 wget 下载文件，但如果我将此 link 放入 Safari，它会成功下载。那个问题的原因是什么？

Answer 1

shell - 不是 wget - 将 & 解释为特殊字符，指示运行后台程序。为避免这种情况，只需将整个 URL 放在引号中，如下所示：

$ wget 'http://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl?file=gfs.t06z.pgrb2.0p25.f000&all_lev=on&all_var=on&subregion=&leftlon=22&rightlon=42&toplat=53&bottomlat=45&dir=/gfs.2015070506'
