[求助](SED提取)RegexBuddy的表达式如何转写成SED的语法?
有以下一段代码

http://[0-9][0-9]\.bak\.115cdn\.com:8080/pickdown.*?(?=") 修改一下复制到cmd命令行中测试.
sed "/http:\/\/[0-9][0-9]\.bak\.115cdn\.com:8080\/pickdown.*?(?=")" text.htm 出现如下语法错误:
sed: -e expression #1, char 70: unterminated address regex 测试过的sed版本包括GNU sed version 4.1.5(含cygwin1.dll的版本) 和GNU sed version 4.2(gnuwin32.sourceforge.net版本,含pcre3.dll-Perl-compatible regular-expression library).
请问正确的语法应该怎样写? 如果上述表达式有sed不支持的参数,应该如何改写(或更好的写法)?
谢谢
