使用剪切和粘贴交换列(using cut and paste to swap column)

使用剪切和粘贴交换列(using cut and paste to swap column)

我有一个像下面的文件，我想交换第二列和第三列。

1425 Juan 14.25 4321 George 21.11 6781 Anna 16.77 1451 Ben 21.77 2277 Tuan 18.77

这是我用过的方式，它可以工作，但它是用两行书写的。

cut -f1,3 test1.txt > cat cut -f2 test1.txt | paste cat -> result

有什么方法可以将它写入一行吗？

评论：不能使用AWK来做到这一点，只能剪切和粘贴。

I got a file like below, I want to swap the second column and the third column.

1425 Juan 14.25 4321 George 21.11 6781 Anna 16.77 1451 Ben 21.77 2277 Tuan 18.77

Here's the way I used, it works but it's written in two lines.

cut -f1,3 test1.txt > cat cut -f2 test1.txt | paste cat -> result

Is there any way that I can write it in one line?

Comments: Cannot use AWK to do that, only cut and paste.

你可以连接命令; 或&& ：

cut -f1,3 test1.txt > cat && cut -f2 test1.txt | paste cat -> result cut -f1,3 test1.txt > cat ; cut -f2 test1.txt | paste cat -> result

或者，使用支持进程替换的shell：

paste <(cut -f1 test1.txt) <(cut -f3 test1.txt) <(cut -f2 test1.txt)

You can just connect the commands with ; or &&:

cut -f1,3 test1.txt > cat && cut -f2 test1.txt | paste cat -> result cut -f1,3 test1.txt > cat ; cut -f2 test1.txt | paste cat -> result

Or, use a shell that supports process substitution:

paste <(cut -f1 test1.txt) <(cut -f3 test1.txt) <(cut -f2 test1.txt)
