Question

我有两个文件，file1.traj和file2.traj。这两个文件都包含相同的数据，数据以相同的格式排列。这两个文件的第一行是注释。在两个文件的第7843行，有笛卡尔坐标X，Y和Z.在第15685行还有另一个笛卡尔坐标X，Y和Z.两个笛卡尔坐标之间的行数是7841.

我想要做的是在整个文件中仅复制从file1.traj到file2.traj的X Y Z坐标。我尝试使用粘贴命令，但我不能单独使用指定的行。

这里我展示了文件中的数据格式。为了清晰起见，我使用了这个数字。

是否有可能使用awk或sed？

Answer 1

使用AWK你可以做到，我不认为它是完美的答案，但它很棘手

sushanth @ mymachine：〜$ cat file1.txt

104.140 159.533  88.303
5.844   4.178   7.821   6.423   4.054   8.578   6.606   4.907   6.827   7.557
4.385   6.722   6.877   6.384   7.283   5.950   6.884   7.565   7.668   6.282
8.474   7.721   7.127   8.928   7.628   7.205   6.259   8.589   6.712   6.110
104.140 159.533  88.303
7.712   8.602   6.643   8.151   8.654   7.495   6.940   7.183   4.871   6.108
7.887   4.864   7.755   7.814   3.754   8.697   7.267   3.724   7.081   7.633
2.478   6.246   8.089   2.604   8.026   8.853   3.943   6.623   5.754   4.529

这里我使用awk

仅使用了35个字符或更长的打印行

sushanth @ mymachine：〜$ cat file1.txt | awk'length＆lt; 35'＆gt; FILE2.TXT

104.140 159.533  88.303
104.140 159.533  88.303

复制并从file1替换为文件特定行
