如何交错来自两个文本文件的行 [英] How to interleave lines from two text files

问题描述

交错两个(或多个)文本文件的行的最简单/最快的方法是什么?示例:

What's the easiest/quickest way to interleave the lines of two (or more) text files? Example:

文件 1:

line1.1
line1.2
line1.3

文件 2:

line2.1
line2.2
line2.3

交错:

line1.1
line2.1
line1.2
line2.2
line1.3
line2.3

当然，编写一个打开它们并完成任务的小 Perl 脚本很容易.但我想知道是否有可能用更少的代码摆脱困境，也许是使用 Unix 工具的单行代码?

Sure it's easy to write a little Perl script that opens them both and does the task. But I was wondering if it's possible to get away with fewer code, maybe a one-liner using Unix tools?

推荐答案

paste -d '
' file1 file2
