－、
下载unix命令工具。gnuwin32 包在 (gnuwin32.sourceforge.net/) 解压后就能使用了。

二、
cd D:\BACKUP\SYSTEM\UNIX\BSD\OpenBSD\packages

三、
gawk "{ print $1 }" e.log | sed -e "s/\-.*//" -e "s/^/wget -c ftp\:\/\/ftp\.openbsd\.org\/pub\/OpenBSD\/4\.6\/packages\/amd64\//g" -e "s/$/*/g" >a.bat

四、
a.bat

后记：
正则表达式中没找到 简单表示带有原字符的字符串，比如用“ftp：//ftp.openbsd.org/pub/OpenBSD/4.6/packages/amd64/" 表示 ftp\:\/\/ftp\.openbsd\.org\/pub\/OpenBSD\/4\.6\/packages\/amd64\/ 的方法。
