使用 awk 在同一个文件中排序多个表

Question

在我的工作流程中，创建了包含带有 two-line header 的简单 table 的文件（参见 post 的末尾）。我想按编号订购这些 tables：

(head -n 2 && tail -n +3 | sort -n -r) > ordered.txt

效果很好，但我不知道如何拆分文件以便我可以订购每个 table 并将其打印在一个文件中。我的做法是：

awk '/^TARGET/ {(head -n 2 && tail -n +3 | sort -n -r) >> ordered.txt}' output.txt

但是，这会导致错误消息。我想避免任何中间输出文件。我的 awk 命令中缺少什么？

输入文件如下所示：

TARGET  1
Sample1 Sample2 Sample3 Pattern
3   3   3   z..........................Z........................................z.........Z...z
147 171 49  Z..........................Z........................................Z.........Z...Z
27  28  13  z..........................Z........................................z.........z...z
75  64  32  Z..........................Z........................................Z.........z...Z

TARGET  2
Sample1 Sample2 Sample3 Pattern
2   0   1   z..........................z........................................z.........Z...Z
21  21  7   z..........................Z........................................Z.........Z...Z
1   0   0   ...........................Z........................................Z.............Z
4   8   6   Z..........................Z........................................z.........Z...z
2   0   1   Z..........................Z........................................Z.........Z....
1   0   0   z..........................Z........................................Z.............Z
1   0   0   z...................................................................Z.........Z...Z

TARGET  3
Sample1 Sample2 Sample3 Pattern
1   0   0   z..........................Z........................................z.............z
1   3   0   z..........................z........................................Z.........Z...Z
1   1   0   Z..........................Z........................................Z.............z
1   0   0   Z..........................Z........................................Z.............Z
0   1   2   ...........................Z........................................Z.........Z...Z
0   0   1   z..........................z........................................z..............

我的输出应该是这样的 - 没有掉落任何一行：

    TARGET  1
Sample1 Sample2 Sample3 Pattern
147 171 49  Z..........................Z........................................Z.........Z...Z
75  64  32  Z..........................Z........................................Z.........z...Z
27  28  13  z..........................Z........................................z.........z...z
3   3   3   z..........................Z........................................z.........Z...z

TARGET  2
Sample1 Sample2 Sample3 Pattern
21  21  7   z..........................Z........................................Z.........Z...Z
4   8   6   Z..........................Z........................................z.........Z...z
2   0   1   z..........................z........................................z.........Z...Z
2   0   1   z..........................z........................................z.........Z...Z
1   0   0   ...........................Z........................................Z.............Z
1   0   0   ...........................Z........................................Z.............Z
1   0   0   ...........................Z........................................Z.............Z

TARGET  3
Sample1 Sample2 Sample3 Pattern
1   0   0   z..........................Z........................................z.............z
1   0   0   z..........................Z........................................z.............z
1   0   0   z..........................Z........................................z.............z
1   0   0   z..........................Z........................................z.............z
0   1   2   ...........................Z........................................Z.........Z...Z
0   0   1   z..........................z........................................z..............

需要 GNU awk array traversal sorting:

gawk '
    BEGIN {PROCINFO["sorted_in"] = "@val_num_asc"} 
    function output_table() {
        for (key in table) print table[key]
        delete table
        i=0
    }
    /TARGET/ {print; getline; print; next} 
    /^$/ {output_table(); print; next} 
    {table[++i] = [=10=]} 
    END {output_table()}
' file

产出

TARGET  1
Sample1 Sample2 Sample3 Pattern
3   3   3   z..........................Z........................................z.........Z...z
27  28  13  z..........................Z........................................z.........z...z
75  64  32  Z..........................Z........................................Z.........z...Z
147 171 49  Z..........................Z........................................Z.........Z...Z

TARGET  2
Sample1 Sample2 Sample3 Pattern
1   0   0   ...........................Z........................................Z.............Z
1   0   0   z...................................................................Z.........Z...Z
1   0   0   z..........................Z........................................Z.............Z
2   0   1   Z..........................Z........................................Z.........Z....
2   0   1   z..........................z........................................z.........Z...Z
4   8   6   Z..........................Z........................................z.........Z...z
21  21  7   z..........................Z........................................Z.........Z...Z

TARGET  3
Sample1 Sample2 Sample3 Pattern
0   0   1   z..........................z........................................z..............
0   1   2   ...........................Z........................................Z.........Z...Z
1   0   0   Z..........................Z........................................Z.............Z
1   0   0   z..........................Z........................................z.............z
1   1   0   Z..........................Z........................................Z.............z
1   3   0   z..........................z........................................Z.........Z...Z

这有点乱，但假设您不想在排序时丢失记录，这应该可行

 awk 'function sortit(){
           x=asort(a)
           for(i=1;i<=x;i++)print b[a[i]" "d[i]++]
           delete(a);delete(b);delete(c);delete(d)
     }                             
     /^[0-9]/{a[[=10=]]=;b[" "c[]++]=[=10=]}
     /TARGET/{print;getline;print}
     !NF{sortit();print}
     END(sortit()}' file

使用 awk 在同一个文件中排序多个表
