我需要使用 shell 脚本创建这两个文件。

答案1

这是一种方法：

$ awk '(/=====/){a=0}
       (/\(Result\)\s*$/){a=1; next} 
       ($1=="Name"){n=$2}
       (a==1){print >> n".txt"}' file

解释

  • (/=====/){a=0}：如果当前行匹配======，则设置a为0。
  • (/\(Result\)\s*$/){a=1; next}: if the current line ends with（结果）followed by 0 or more whitespace, seta to1`并跳到下一行。
  • ($1=="Name"){n=$2}：如果第一个字段是Name，则将n变量设置为第二个字段的值。
  • (a==1){print >> n".txt"：如果a是，则将此行打印到名为（名称）且扩展名为1的文件中。n.txt

答案2

#!/bin/bash

filename=""
do_write=0

while read line
do
  case $line in
    ==*Result*) do_write=1
                ;;
      ==*Test*) do_write=0
                filename=""
                ;;
         Name*) [[ $do_write == 0 ]] && filename=${line#Name }.txt
                ;;
            "") # Skip blank lines
                ;;
             *) [[ $do_write == 1 ]] && echo "$line" >> $filename
  esac
done

使用您的输入文件：

$ head -10 input
====== 20160606:034441 ====== Mango(Test)
TestName     MangoT
Row  0
Season N
Name Safeda
Location    Delhi

====== 20160606:034441 ====== Mango(Result)
TestName     MangoR
Result  0

我们得到结果：

$ ./parse < input

$ ls
Alphonso.txt  input  parse   Safeda.txt

$ head Alphonso.txt
TestName     MangoR
Result  0
No_of_Mango 13
Quantity    5
Quantity    3
Quantity    1
Quantity    0
Quantity    7
Quantity    8
Quantity    70    

$ head Safeda.txt
TestName     MangoR
Result  0
No_of_Mango 13
Quantity    2
Quantity    3
Quantity    6
Quantity    0
Quantity    1
Quantity    9
Quantity    54
