File1.txt 有两列，File2.txt 有四列。我想加入两个具有唯一 id 的文件（array[1] 应该在两个文件（file1.txt 和 file2.txt）中匹配，并仅给出匹配的 id 输出（请参阅 output.txt）。

我努力了join -v <(sort file1.txt) <(sort file2.txt)。请求有关 awk 或 join 命令的任何帮助。

答案1

join效果很好：

$ join <(sort File1.txt) <(sort File2.txt) | column -t | tac
 id                           No       P   R   S
 gi|371443198|gb|JH556662.1|  7573913  2   2   0
 gi|371440577|gb|JH559283.1|  6931777  21  19  2

附注输出列顺序重要吗？

如果是，请使用：

$ join <(sort 1) <(sort 2) | tac | awk '{print $1,$3,$4,$5,$2}' | column -t
 id                           P   R   S  No
 gi|371443198|gb|JH556662.1|  2   2   0  7573913
 gi|371440577|gb|JH559283.1|  21  19  2  6931777

答案2

一种使用方法awk：

内容script.awk：

## Process first file of arguments. Save 'id' as key and 'No' as value
## of a hash.
FNR == NR {
    if ( FNR == 1 ) { 
        header = $2
        next
    }   
    hash[ $1 ] = $2
    next
}

## Process second file of arguments. Print header in first line and for
## the rest check if first field is found in the hash.
FNR < NR {
    if ( $1 in hash || FNR == 1 ) { 
        printf "%s %s\n", $0, ( FNR == 1 ? header : hash[ $1 ] ) 
    }   
}

像这样运行它：

awk -f script.awk File1.txt File2.txt | column -t

结果如下：

id                           P   R   S  NO
gi|371443198|gb|JH556662.1|  2   2   0  7573913
gi|371440577|gb|JH559283.1|  21  19  2  6931777
