我在这里看到了对前一个SO问题的引用：How to paste columns from separate files using bash?

但由于某种原因，粘贴和 pr 命令对此数据集都不起作用：而paste -d <(cut -d "," -f 3,7 f1) <(cat f2)只是在前面附加一个逗号每一行f2

pr -mts,产生与粘贴相同的行为。

有关为何这些文件行为不同的任何建议？

谢谢！

Answer 1

请注意，您错过了-d选项的值。

将第3列和第7列放在＆＃34; f2＆＃34;的开头。行，用逗号分隔

paste -d, <(cut -d, -f 3,7 f1) f2

核算CRLF行结尾

paste -d, <(sed 's/\r$//' f1 | cut -d, -f 3,7) <(sed 's/\r$//' f2)

Answer 2

将两个答案（来自jaypal的评论+格伦的答案）结合在一起，最终的答案结果是，CR的结束。

要获得整体答案，诊断此问题的一种方法是

file filename

如果它返回ASCII text, with CRLF line terminators之类的内容，那么您就知道自己遇到了这个问题。 CR ='\ r'，LF ='\ n'，所以实际上每一行都以'\ r \ n'结尾。

运行tr -d, "\r" < f1 > tmp && mv tmp f1将从代码中删除所有额外的'\ r'，然后允许粘贴按预期工作。

使用粘贴或PR无法在命令行上连接列
