求助！两个文本之间字符匹配后局部段落替换的问题

moto1717

大家好，头一次发帖，请大家多指教。本人非专业编程人员，最近在研究sed，感觉很方便的工具，可以快速解决一些重复的工作。只是本人很难在深入研究，所以请教大家下面的问题：
现在有2个文件aaa.txt和bbb.txt。

aaa.txt的内容是：
HKFJ 210700Z 15002MPS 5000 BR NSC 10/09 Q1025 NOSIG
FKHJ 210700Z 07006MPS 9999 -RA SCT040 10/M00 Q1020 NOSIG

bbb.txt的内容是：
HKFJ::HKFJ 100030Z 09010MPS CAVOK 13/05 Q1027 NOSIG::HKFJ 092240Z 100009 33006G11MPS CAVOK BECMG 0506 33004MPS::292,009,07.5/312,021,03.3/324,028,-00.3/314,033,-04.6/295,035,-18.8/286,042,-31.3/286,052,-43.3/284,066,-50.9/279,081,-55.2/275,088,-55.7/272,076,-63.2<br>FKHJ::FKHJ 100000Z 16001MPS CAVOK 02/M01 Q1030 NOSIG::FKHJ 091935Z 100024 33004MPS CAVOK::351,007,07.2/347,007,01.7/335,016,01.1/326,026,-05.6/312,040,-18.5/308,044,-31.2/295,043,-44.5/287,051,-52.1/283,068,-57.5/278,075,-57.2/276,068,-63.0<br>
aaa文件都是单独成行，bbb文件都是混在一起的一行。

我的问题是能否用sed将aaa文件的每行匹配到bbb文件中相应的红色部分并替换呢？我用的是sed for windows版。谢谢各位。

请高手帮帮忙

说实话我没看懂 “将aaa文件的每行匹配到bbb文件中相应的红色部分并替换” 是需要干嘛。。
所以为了避免大家去猜，你不如把你想要的结果贴出来还直观些

3楼大神说的对啊，就是啊，，
aaa里没有字符和bbb文件相同啊

感谢你回复，这就是我要的结果啊。就是aaa的HKFJ行替换bbb的红色部分，aaa的FKHJ行替换bbb的红色部分。

感谢你的回复，我就是想通过与aaa里面的前4个字符匹配的比如HKFJ,然后把整行替换到bbb的相应位。，
