我的input.txt文件内容如下：
100a0.35s-darw.txt
100a0.35s.txt
100a0.45s-darw.txt
100a0.45s.txt
100a0.55s-darw.txt
100a0.55s.txt
200a0.35s-darw.txt
200a0.35s.txt
200a0.45s-darw.txt
200a0.45s.txt
200a0.55s-darw.txt
200a0.55s.txt
400a0.35s-darw.txt
400a0.35s.txt
400a0.45s-darw.txt
400a0.45s.txt
400a0.55s-darw.txt
400a0.55s.txt
50a0.35s-darw.txt
50a0.35s.txt
50a0.45s-darw.txt
50a0.45s.txt
50a0.55s-darw.txt
50a0.55s.txt
........


我想每次依次复制两行到另一个文件input1.txt,第二次复制的时候覆盖。该如何做呢？
