请教unix环境下如何将A文件中部分内容替换B文件中的相同部分

encguwe

谢谢，可是这个-r参数在这里好像有问题

eric@ahmas1o> sed -r '/<measInfo measInfoId/{:a;N;/\n<measInfo measInfoId/;s#^.*$#sed -n '/measInfo/,/measInfo/p' a.txt#e}' b.txt
sed: illegal option -- r

    是不是环境不同，我是solaris Unix 的

eric@ahmas1o> awk -vs=$s -ve=$e -vp=1 '$0~s,$0~e{if(FNR==NR){y=$0~e?y$0:y$0"\n"}else{p=0}}FNR==NR{next}$0~e{p=1;print y;next}p' a.txt b.txt
s: Undefined variable.

可能是吧，solaris我没用过，我测试环境是红帽子linux，但这是awk比较基本传参写法，应该支持吧，只好坐等大神了。。。

用nawk试试；或者用绝对路径执行.

    用了nawk，貌似语法对了，但是生成的文件没有换行，如何解决呢？
