Question

我有两个文件

file1.txt（由用户注册生成）

1   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
2   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
3   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
4   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS

file2.txt（由用户作业提交生成，只有一行）

CellPhone   MLSNUMBER   PRICE   ANDANOTHER20FIELDS

两个文件中的CellPhone编号始终采用相同的格式3215551234

我想在file1.txt中搜索CellPhone编号，并将完整的特定行添加到file2.txt的开头

我在最后一天左右用awk和sed得到了这么远，但这让我很难过。我相信awk和join就是这样，但这超出了我的技能水平。

Answer 1

join会更改您的字段并需要排序的文件。听起来你正在寻找更像这样的东西：

grep " $(awk '{print $1}' file2.txt) " file1.txt|cat - file2.txt

假设file1.txt中的CellPhone号码周围有空格。

Answer 2

如果您想在file1.txt中搜索file2.txt手机号码：

$ awk '
  # Only runs on the first file (file2.txt)
  NR==FNR {
    # Register each phone number in an array
    cp[$1]=1
    # Skip the next part of the execution
    next
  }
  # Only running for file1.txt
  # Check to see if the phone number in file1.txt is in the array
  $4 in cp # This is a short way of writing: $4 in cp {print $0};
' file2.txt file1.txt
1   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
2   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
3   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
4   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS

如果你想在最后连接file2.txt，你可以简单地写| cat - file2.txt：

awk 'NR==FNR{cp[$1]=1;next}$4 in cp' file2.txt file1.txt | cat - file2.txt

如果您在file2.txt中有多个电话号码，并希望输出为：

1 Name1 Name2 Phone1 Email ...
2 Name1 Name2 Phone1 Email ...
Phone1   MLSNUMBER   PRICE   ANDANOTHER20FIELDS
3 Name1 Name2 Phone2 Email ...
4 Name1 Name2 Phone2 Email ...
Phone2   MLSNUMBER   PRICE   ANDANOTHER20FIELDS

如果 - 假设file1.txt预先按电话号码排序：

，则可以使用此项

$ awk '
  # Only runs on the first file (file2.txt)
  NR==FNR {
    # Register each phone number in an array
    cp[$1]=$0
    # Skip the next part of the execution
    next
  }
  # Print current line same as 1==1{print $0}
  1;
  FNR>1 && prev!=$4 {
    print prevLine
  }
  {
    prev=$4
    prevLine=cp[$4]
  }
  END {
    print prevLine
  }
' file2.txt file1.txt 
1 Name1 Name2 Phone1 Email ...
2 Name1 Name2 Phone1 Email ...
1   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
Phone1   MLSNUMBER   PRICE   ANDANOTHER20FIELDS
2   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
3   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
4   Name1   Name2   CellPhone   Email   ANDANOTHER20FIELDS
CellPhone   MLSNUMBER   PRICE   ANDANOTHER20FIELDS

提取file1.txt行并使用shell合并到file2.txt？
