并排显示两个文件 [英] Display two files side by side

问题描述

如何在 shell

给定 one.txt 和 two.txt ：

$ cat one.txt
apple
pear
longer line than the last two
last line

$ cat two.txt
The quick brown fox..
foo
bar 
linux

skipped a line

显示：

apple                               The quick brown fox..
pear                                foo
longer line than the last two       bar 
last line                           linux

                                    skipped a line

粘贴one.txt two.txt 因为它只是在第1列和第2列之间打印一个标签。我知道如何使用emacs和vim，但希望输出显示到stdout管道系统。

paste one.txt two.txt almost does the trick but doesn't align the columns nicely as it just prints one tab between column 1 and 2. I know how to this with emacs and vim but want the output displayed to stdout for piping ect.

我想出的解决方案使用 sdiff 然后管道sed以删除输出 sdiff 补充说。

The solution I came up with uses sdiff and then pipes to sed to remove the output sdiff adds.

sdiff one.txt two.txt | sed -r'/ [<> || /// s /（\ t）{3} //'

我可以创建一个函数，并将其粘贴在我的 .bashrc ，但肯定有一个命令已经存在（或潜在的一个更清洁解决方案） / p>

I could create a function and stick it in my .bashrc but surely a command for this exists already (or a cleaner solution potentially)?

推荐答案

您可以使用 pr $ c> -m 标志合并文件，每列一个， -t 可省略标题，例如

You can use pr to do this, using the -m flag to merge the files, one per column, and -t to omit headers, eg.

pr -m -t one.txt two.txt

输出：

apple                               The quick brown fox..
pear                                foo
longer line than the last two       bar
last line                           linux

                                    skipped a line
