wget 遇到有轉址時, save 的檔名可能會不正確
例如:
# wget http://hk1.php.net/get/php-5.6.11.tar.bz2/from/this/mirror
--2015-07-22 14:32:35-- http://hk1.php.net/get/php-5.6.11.tar.bz2/from/this/mirror

加 --content-disposition 就會讓 save 的檔名是正確的
# wget --content-disposition http://hk1.php.net/get/php-5.6.11.tar.bz2/from/this/mirror

--content-disposition
If this is set to on, experimental (not fully-functional) support for "Content-Disposition" headers is enabled.
This can currently result in extra round-trips to the server for a "HEAD" request,
and is known to suffer from a few bugs, which is why it is not currently enabled by default.
This option is useful for some file-downloading CGI programs that use "Content-Disposition"
headers to describe what the name of a downloaded file should be.
