上面的文本一共只有4行，如果有多的换行请删除掉。
这样的一段文字，现在需要用一个正则截取http://pic.fsrow.com/pic 一直到 xxx.jpg这段文字   （如  http://pic.fsrow.com/pic/user_1506/store_15/desc/ 01450517001.files/page1_1296052297.jpg）
由于一个行里有多次这样的文字  http://pic.fsrow.com/pic 一直到 xxx.jpg  ，  不知道怎么用一个正则准确的提取出来，尽量简短一些，麻烦高手指导一下

yinyuemi

grep -Po 'http://pic.fsrow.com/pic.*\.jpg'

RE_HASH

$_=$str;
s/\r|\n//g;
@result =/(http:\/\/pic.fsrow.com\/pic.+?.jpg)/g;
print join "\n", @result;

sai9924

grep -Po xxx.jpg后面紧接着的字符串也一起显示，
有没有一个正则能准确的截取字段
