当某些列在 2 个文件之间匹配时，如何将列从文件 2 复制到文件 1

  • 772

我有一个文件

head top_candidates
    25 elevation_e gene1 20 9 0.0246022994932004 5 8 10.9217937824527
    30 elevation_e gene1 59 18 0.0246022994932004 7 12 15.653559774527
    31 elevation_e gene3 34 10 0.0246022994932004 6 9 9.47018201139585
    108 elevation_e gene3 18 6 0.0246022994932004 4 7 6.86419248099239

和另一个文件

head genes.bed
Chr00c0001  52974   70567   gene1
Chr00c0003  32983   33237   gene2
Chr00c0003  36241   36792   gene3
Chr00c0003  100286  101468  gene4
Chr00c0004  80876   93710   gene5

当文件 2 (gene1,2,..) 的第 4 列与文件 1 的第 3 列匹配时，我想将第二个文件的第 1,2 和第 3 列粘贴到第一个文件。

我想要的输出：

head desired
25 elevation_e gene1 20 9 0.0246022994932004 5 8 10.9217937824527 Chr00c0001    52974   70567
