Question

来自wget手册页

‘-i file’
‘--input-file=file’
     Read urls from a local or external file. If ‘-’ is specified as file, urls
     are read from the standard input. (Use ‘./-’ to read from a file literally
     named ‘-’.)

     If this function is used, no urls need be present on the command line. If
     there are urls both on the command line and in an input file, those on the
     command lines will be the first ones to be retrieved. If ‘--force-html’ is
     not specified, then file should consist of a series of URLs, one per line.

我试过

wget -i - www.google.com

它下载了一个文件index.html，但随后它就会挂起。甚至在我按下之后多次“输入”，它仍然挂起。为什么呢？

wget从标准输入读取输入
