Linux bash 使用所有可用行将两个文本文件编织成一个替代行

Question

我希望将两个文本文件合并为一个，一个文本文件中的所有行都变成奇数行号另一个文件变成偶数行号比如将文件编织在一起

input1.txt

1, 267, Note_on_c, 0, 67, 100
1, 758, Note_on_c, 0, 58, 100
1, 1248, Note_on_c, 0, 79, 100
1, 1739, Note_on_c, 0, 52, 100

input2.txt

1, 368, Note_off_c, 0, 67, 127
1, 936, Note_off_c, 0, 58, 127
1, 1415, Note_off_c, 0, 79, 127
1, 1917, Note_off_c, 0, 52, 127

并且需要组合这些文本文件来创建以下输出

1, 267, Note_on_c, 0, 67, 100
1, 368, Note_off_c, 0, 67, 127
1, 758, Note_on_c, 0, 58, 100
1, 936, Note_off_c, 0, 58, 127
1, 1248, Note_on_c, 0, 79, 100
1, 1415, Note_off_c, 0, 79, 127
1, 1739, Note_on_c, 0, 52, 100
1, 1917, Note_off_c, 0, 52, 127

所以我希望合并这些文件，因为 weave

Answer 1

使用 GNU sed 的 R 命令：

sed 'R input2.txt' input1.txt

输出：

1, 267, Note_on_c, 0, 67, 100
1, 368, Note_off_c, 0, 67, 127
1, 758, Note_on_c, 0, 58, 100
1, 936, Note_off_c, 0, 58, 127
1, 1248, Note_on_c, 0, 79, 100
1, 1415, Note_off_c, 0, 79, 127
1, 1739, Note_on_c, 0, 52, 100
1, 1917, Note_off_c, 0, 52, 127

来自man sed：

R filename: Append a line read from filename. Each invocation of the command reads a line from the file. This is a GNU extension.

另一种选择是使用 paste 和换行符作为分隔符

paste -d '\n' input1.txt input2.txt

1, 267, Note_on_c, 0, 67, 100
1, 368, Note_off_c, 0, 67, 127
1, 758, Note_on_c, 0, 58, 100
1, 936, Note_off_c, 0, 58, 127
1, 1248, Note_on_c, 0, 79, 100
1, 1415, Note_off_c, 0, 79, 127
1, 1739, Note_on_c, 0, 52, 100
1, 1917, Note_off_c, 0, 52, 127

来自man paste：

Write lines consisting of the sequentially corresponding lines from each FILE
