Question

我有一个具有n行数的文件，我希望它的数据按照以下顺序分布在7个文件中

**我的输入文件有n行，这只是一个例子。

输入文件

输出文件

 1  2  3  4  5 6  7
14 13 12 11 10 9  8 
15 16 17 18 19 20 21
28 27 26 25 24 23 22

所以如果我打开第一个文件，它应该有行

类似地，如果我打开第二个文件，它应该具有行

其他文件的输出也类似。

任何人都可以帮忙，用下面的代码执行所需的操作，但不是按所需的顺序进行。

awk '{print > ("te1234"++c".txt");c=(NR%n)?c:0}' n=7 test6.txt

1  2  3  4  5  6  7
8  9  10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28

Answer 1

编辑： ：由于OP更改了Input_file的示例完全不同，因此现在添加此解决方案，因此仅编写并测试了所示示例。

带有xargs和单个awk： （推荐一个）

xargs -n7 < Input_file | 
awk '
FNR%2!=0{
  for(i=1;i<=NF;i++){
    print $i >> (i".txt")
    close(i".txt")
  }
  next
}
FNR%2==0{
   for(i=NF;i>0;i--){
     count++
     print $i >> (count".txt")
     close(i".txt")
   }
   count=""
}'

初始解决方案：

xargs -n7 < Input_file | 
awk '
FNR%2==0{
  for(i=NF;i>0;i--){
    val=(val?val OFS:"")$i
  }
  $i=val
  val=""
}
1' | 
awk '
{
  for(i=1;i<=NF;i++){
    print $i >> (i".txt")
    close(i".txt")
  }
}'

以上也可以用单个awk完成，也将在几分钟内添加xargs + awk（单个）解决方案。

您可以尝试按照GNU awk中的示例进行跟踪，编写和测试。

awk '{for(i=1;i<=NF;i++){print $i >> (i".txt");close(i".txt")}}' Input_file

Answer 2

输出文件计数器可能会每隔7个第二组下降一次：

awk 'FNR%n==1 {asc=!asc}
    {
        out="te1234" (asc ? ++c : c--) ".txt";
        print >> out;
        close(out)
    }' n=7 test6.txt

Answer 3

$ ls
file    tst.awk

$ cat tst.awk
{ rec = (cnt % 2 ? $1 sep rec : rec sep $1); sep=FS }
!(NR%n) {
    ++cnt
    nf = split(rec,flds)
    for (i=1; i<=nf; i++) {
        out = "te1234" i ".txt"
        print flds[i] >> out
        close(out)
    }
    rec=sep=""
}

。

$ awk -v n=7 -f tst.awk file

。

$ ls
file        te12342.txt te12344.txt te12346.txt tst.awk
te12341.txt te12343.txt te12345.txt te12347.txt

$ cat te12341.txt
1
14
15
28

$ cat te12342.txt
2
13
16
27

如果输入的内容不是n的整数倍，则将!(NR%n)块中当前的代码移到函数中，然后在其中的END部分中调用该函数

这可能对您有用（GNU sed和并行）：

        X509Certificate2 certificate = FindCertificate(Thumbprint);

        PdfReader reader = new PdfReader(document);

        //Append mode
        PdfStamper st = PdfStamper.CreateSignature(reader, new FileStream(SignedDocumentPath(document), FileMode.Create, FileAccess.Write), '\0', null, true);


        int signatureWidth = 250;
        int signatureHeight = 100;       
        int NewXPos = 0;
        int NewYPos = 0;

        SetStampCoordinates(reader, st, ref NewXPos, ref NewYPos, signatureWidth, signatureHeight);            

        PdfSignatureAppearance sap = st.SignatureAppearance;

        if (reader.AcroFields.GetSignatureNames().Count == 0)
        {
            SetSignatureFieldOptions(certificate, sap, reader, "1", 1, NewXPos, NewYPos, signatureWidth, signatureHeight);
        }
        else {

        ct.Go();

创建一个sed脚本以写入名为filen的文件，其中n为1到7（请参见上面的并行命令以及粘贴命令中的第一组参数）。

sed脚本使用parallel 'echo {1}~14w file{1}; echo {2}~14w file{1}' ::: {1..7} :::+ {14..8} | sed -n -f - file && paste file{1..7}地址，其中n~m是起始地址，而n是其后的模。

首先创建分布式文件，然后粘贴命令将它们全部连接在一起以生成单个输出文件（默认情况下，制表符分隔，使用粘贴m选项可获得所需的定界符）。

使用Bash和sed的替代方法：

-d

以递增和递减顺序分配数据
