加入3档由第一列与加盟（AWK是）？ [英] join 3 files by first Column with join (was awk)?

问题描述

我有三个类似的文件，他们都是这样的：

i have three similar files, they are all like this:

ID1 Value1a
ID2 Value2a
  .
  .
  .
IDN Value2n

，我想这样的输出

and i want an output like this

ID1 Value1a Value1b Value1c
ID2 Value2a Value2b Value2c
.....
IDN ValueNa ValueNb ValueNc

寻找到第一线，我想value1A是在的fileA ID1的值时，value1B ID1中FILEB值，依此类推，其中每个字段和每一行。我这吼声像SQL JOIN。我试过几件事情，但没有人在那里甚至接近。

Looking to the first line, i want value1A to be the value of id1 in fileA, value1B the value of id1 in fileB, and so on which each field and each line. I thougth it like a sql join. I've tried several things but none of them where even close.

编辑：所有文件具有相同的长度和IDS

All files have the same length and ids.

推荐答案

（1）一试

join fileA fileB | join - fileC
