Linux 如何循环浏览3个文件，搜索特定字符串并使用bash将其与另一个文件中的字符串匹配

我有3个文本文件，我必须用于以下代码。它们是：subscribers.txt、towns.txt和calls.txt

Subscribers.txt的格式为：

 callerID|name |gender|birthYear|hometownID|email
 10000025|kgosi|F     |1981     |33        |10000025@cs.ub.bw

date      |time    |duration|calleeID|callerID|locationOfcallee|locationOfcaller
18/02/2005|19:25:27|257     |10000025|10000017|3               |28

Town.txt的格式如下：

hometownID|townName   |location
28        |Ramatlabama|B

calls.txt的格式为：

 callerID|name |gender|birthYear|hometownID|email
 10000025|kgosi|F     |1981     |33        |10000025@cs.ub.bw

date      |time    |duration|calleeID|callerID|locationOfcallee|locationOfcaller
18/02/2005|19:25:27|257     |10000025|10000017|3               |28

我创建了一个函数，该函数将callerID作为参数，然后打印出该callerID发出的调用。如何修改以下代码，使其能够从键盘读取callerID，显示该callerID的所有调用。显示所有调用之前的第一行必须包含：callerID、name（来自subscribers.txt）、age（从subscribers.txt中获取出生年份并计算年龄）、性别（从subscribers.txt中）和汤名（从towns.txt中）

代码是：

 #!/bin/bash

    echo "enter caller id "
    read  x
    exec 401<> calls.txt       # open calls.txt file  
    exec 402<> subscribers.txt #opens  subscribers.txt
    exec 403<> town.txt #opens tows.txt
    while  read line <&402 #reading from subscribers.txt
    do
    {



        callerid=${line%%|*}; # cut off the rest of $line but keep callerid
        line=${line#*|};       

        name=${line%%|*}; # cut off the rest of $line but keep time of name
        line=${line#*|};      e



        gender=${line%%|*};  # cut off the rest of $line but keep box
        line=${line#*|};       

        year=${line%%|*};   # cut off the rest of $line but keep town
        line=${line#*|};      


        hometown=${line%%|*};   # cut off the rest of $line but keep phone
        line=${line#*|};     


        email=${line%%|*};   # cut off the rest of $line but keep email
        line=${line#*|};



    if [ $callerid = "$x" ]
    then 

        echo $callerid "|" $name "|" $gender "|" $hometown ;
     echo " $callerid "|" $name "|" $gender "|" $hometown">>${x}outgoingcalls.log #stores in this file

    fi

    }
    done
    exec 402>&-


    while read line <&401      # read a line at a time from calls.txt
    do                         # if end of file reached, while will yield false then terminate
    {
        full_line=$line;       # because $line is going to change, store it somewhere


        date=${line%%|*}; # cut off the rest of $line but keep date  
        line=${line#*|};      



        time=${line%%|*}; # cut off the rest of $line but keep time    
        line=${line#*|};       



        duration=${line%%|*};  # cut off the rest of $line but keep duration
        line=${line#*|};       



        callee=${line%%|*};   # cut off the rest of $line but keep callee
        line=${line#*|};      


        caller=${line%%|*};   # cut off the rest of $line but keep phone
        line=${line#*|};      

        ### extract phone
        calleeLoc=${line%%|*};   # cut off the rest of $line but keep callee location
        line=${line#*|};



        ### extract phone
        callerLoc=${line%%|*};   # cut off the rest of $line but keep caller location
        line=${line#*|};

        if [ $caller = "$x" ];
          then

                 echo $date"|"$time"|"$duration"|"$callee"|"$caller"|"$calleLoc"|" $callerLoc
            echo "$date:$time:$duration:$callee:$caller:$calleeLoc:$callerLoc>>${x}outgoingcalls.log #stores in this file
        fi


    }
    done


    exec 401>&-

！/bin/bash
回显“输入来电显示”
读x
exec 401 calls.txt#open calls.txt文件
exec 402 subscribers.txt#打开subscribers.txt
exec 403 town.txt打开tows.txt
在读取行>${x}outgoingcalls.log时，存储在此文件中
fi
}
完成
exec 402>&-
在read line中，您的脚本在与给定输入进行匹配之前正在处理每一行呼叫和订户。在处理它们之前，使用grep查找相关行更为明智

！/bin/bash
echo-n“输入呼叫者id：”
读取呼叫者id
caller\u details=$（grep-m1“$caller\u id”subscribers.txt）
调用方名称=$（echo$调用方详细信息| cut-d\|-f2）
来电者年龄=$（$（日期+%Y）-$（回显$caller_详情| cut-d\|-f4）））
caller|u town=$（grep-m1“$（echo$caller|u details | cut-d\|-f5）“towns.txt | cut-d\|-f2）
printf“来电显示：%s |姓名：%s |年龄：%s |城镇：%s\n”“$Caller | ID”“$Caller | Name”“$Caller | Age”“$Caller | Town”
回声“========================================================================================================================================================================================================================================================================================================================================================================
printf“%-10s |%-8s |%-3s |%-16s |%-16s |%-16s |%s\n”“日期”“时间”“Dur”“Callee”“Caller”“Callee Town”“Caller Town”
对于$（awk-v id=“$caller_id”-F'|''$5==id'calls.txt）中的调用，执行以下操作
调用日期=$（回显“$call”| cut-d\|-f1）
调用时间=$（回显“$call”| cut-d\|-f2）
呼叫持续时间=$（回显“$call”| cut-d\|-f3）
被调用方=$（grep-m1“$（echo“$call”| cut-d\|-f4）”subscribers.txt | cut-d\|-f2）
callee|u town=$（grep-m1“$（echo“$call”| cut-d\|-f6）”towns.txt | cut-d\|-f2）
调用方| town=$（grep-m1“$（echo“$call”| cut-d\|-f7）”towns.txt | cut-d\|-f2）
printf“%s |%s |%-3s |%-16s |%-16s |%-16s |%s\n”“$call|u date”“$call|u time”“$call|u duration”“$callee”“$caller|u name”“$callee|u town”“$caller|u town”
完成
