如何使用unix将一个csv文件内容映射到第二个csv文件并写入另一个csv

问题描述

| 编写了一些unix脚本后，我能够设法将数据从不同的xml文件获取为csv格式，现在我陷入了以下问题 file1.csv：包含

1,5,6,7,8
2,3,4,9
1,10,11,12
1,12

file2.csv：包含

1,Mango,Tuna,Webby,Through,Franky,Sam,Sumo
2,Franky
3,Sam
4,Sumo
5,Webby
6,Through
7,Sumo
8,Nothing
9,Sumo
10,Sumo,Tuna
11,Through
12,Franky

我想要的输出是

1,8
Mango,Sumo
Mango,Webby
Tuna,Through
Through,Sumo
Nothing
Common word:None

2,9
Franky
Sam
Sumo
Mango,Webby
Sam,Sumo
Common Word:None

1,12
Mango,Sumo
Tuna,Through
Sumo,Tuna
Mango,Through
Mango,Franky
Common word: Tuna

1,Webby
Mango,Franky
Common word: Mango,Webby

我感谢您的帮助。 谢谢 我有一些解决方案，但还不完整

##!/bin/bash
count=1
count_2=1
for i in `cat file1.csv`
do
    echo $i > $count.txt
    cat $count.txt | tr \",\" \"\\n\" > $count_2.txt
    count=`expr $count + 1`
    count_2=`expr $count_2 + 1`
done;
#this code will create separte files for each line in file1.csv,bash file3_search.sh

##!/bin/bash
cat file2.csv | sed \'/^$/d\' | sed \'s/[ ]*$//\' > trim.txt
dos2unix -q 1.txt 1.txt
dos2unix 2.txt 2.txt
dos2unix 3.txt 3.txt
echo \"1st Combination results\"
for i in `cat 1.txt`
do
cat trim.txt | egrep -w $i
done > Combination1.txt;
echo \"2nd Combination results\"
for i in `cat 2.txt`
do
    cat trim.txt | egrep -w $i
done > Combination2.txt;
echo \"3rd Combination results\"
for i in `cat 3.txt`
do
    cat trim.txt | egrep -w $i
done > Combination3.txt;

伙计们，我不擅长编程（我是软件测试人员），请有人可以重构我的代码，也请告诉我如何在这些Combination.txt文件中获取常用词     

解决方法

        恕我直言，它的工作原理：

for line in $(cat 1.csv) ; do 
    echo $line ; 
    grepline=`echo $line | sed \'s/ \\+//g;s/,/,|/g;s/^\\(.*\\)$/^(\\1,)/\'`; 
    egrep $grepline 2.csv
    egrep $grepline 2.csv | \\
    awk -F \",\" \'
      { for (i=2;i<=NF;i++) 
          {s[$i]+=1} 
      }
      END { for (key in s) 
              {if (s[key]==NR) { tp+=key \",\" } 
              } 
            if (tp!=\"\") {print \"Common word(s): \" gensub(/,$/,\"\",\"g\",tp)} 
              else {print \"Common word: None\"}}\'
   echo
done

高温超导     ,        这是您的答案。它取决于bash版本4的关联数组功能：

IFS=,declare -a words

# read and store the words in file2
while read line; do
    set -- $line
    n=$1
    shift
    words[$n]=\"$*\"
done < file2.csv

# read file1 and process
while read line; do
    echo \"$line\"

    set -- $line
    indexes=( \"$@\" )
    NF=${#indexes[@]}
    declare -A common

    for (( i=0; i<$NF; i++)); do
        echo \"${words[${indexes[$i]}]}\"

        set -- ${words[${indexes[$i]}]}
        for word; do
            common[$word]=$(( ${common[$word]} + 1))
        done
    done

    printf \"Common words: \"
    n=0
    for word in \"${!common[@]}\"; do
        if [[ ${common[$word]} -eq $NF ]]; then
            printf \"%s \" $word
            (( n++ ))
        fi
    done
    [[ $n -eq 0 ]] && printf \"None\"

    unset common
    printf \"\\n\\n\"
done < file1.csv
