awk在文件1的序列中找到丢失的数字，并将其追加到文件2中的列

Question

hi正如前一个问题中所建议的，我将尝试更多地阐明我想要实现的目标。与文件1中一样，在第4列中，我有一些数字不是连续排序的，比如1,2,3,4,5..，这意味着我需要打印那些缺失的，例如在3号之后，我应该在上得到4号等等

cat文件1

A R5 A48 1
B R5 A48 2
C R4 A48 3
D R8 A48 15
E R9 A48 22
F R20 B55 21
G R55 B22 19
R B1 I77 14
AA B8 PP 18
BX A255 PA 7
CA A77 PB 10
WW W7 PX 11

我在这架返回的飞机上找到了部分解决方案

arr=($(awk '{ print $4 }' file1 )) | printf '%sn' ${arr[*]}| 
awk -v first=1 -v last=23 ' BEGIN {for(i=first; i<=last; i++) array[i] = 1} 
{for(i=1;i<=NF;i++) array[$i] += 1} END {for (num in array) if (array[num] == 0) print num}'
4
5
6
8
9
12
13
16
17
20
23

这就是我想要的，但我仍然错过了打印23号之后到31号的剩余数字，并根据文件2的行数/行数将其粘贴为列$3(3号(

cat文件2

例如，如果下一个文件2将有22行/行，则它将添加数字直到32，例如

我认为应该用更好的方法来完成，将file1列$4中的数字也放入数组中，并重新映射逻辑

awk前往救援！无需在脚本中插入bash。awk是一种成熟的编程语言，尤其适用于文本处理。

请注意，19在您的第一个文件中，因此它在输出中被跳过。您的输出与给定输入的规范不一致。
