需要输出:0200000480205A所在行开始的内容到A文本
其他内容输出到B文本

我现在想到的是先找到:0200000480205A所在行，在执行输出操作，但是需要做两次搜索操作，效率较低，
请问有没有只用一次搜索操作就完成需求的代码？

你好请问只要匹配一行前几个字符，该怎么写条件呢？

文件比较大的话，推荐试试 sed.exe 这个第三方命令行工具：
http://bcn.bathome.net/tool/4.8/sed.exe

sed "0,/:0200000480205A/!d" "1.txt" | sed "$d" > "A.txt"
sed "/:0200000480205A/,$!d" "1.txt" > "B.txt"

文件比较大的话，推荐试试 sed.exe 这个第三方命令行工具：

sed "0,/S32580200000/!d" "1.txt" | sed "$s/.*/S7058010020068/" > "A.txt"
