在bash数组的数组 [英] Array of arrays in bash

问题描述

我试图读取其中包含了句号隔开的字段行中输入文件行。
我希望把它们放进一个数组的数组这样我就可以通过他们循环以后。输入似乎是好的，但推是到阵列（INDATA）似乎并不奏效。

在code云：

 输入文件：
GSDB.GOSALESDW_DIST_INVENTORY_FACT.MONTH_KEY
GSDB.GOSALESDW_DIST_INVENTORY_FACT.ORGANIZATION_KEY
INFILE = $ {1}OIFS = $ IFS
IFS =：猫$ {INFILE} |而读线
做
      行= $ {行//\\./：}
      inarray =（$ {}行）
＃回声$ {inarray [@]}
＃回声$ {＃inarray [@]}
＃回声$ {inarray [0]}
＃回声$ {inarray [1]}
＃回声$ {inarray [2]}      INDATA =（$ {INDATA [@]}$ {inarray [@]}）
DONE
IFS = $ OIFS回声$ {＃INDATA [@]}为（（i = 0; I＆LT; $ {＃INDATA [@]};我+ +））
做
 回声$我
    为（（J = 0; J＆LT; $ {＃INDATA [$ i] [@]}; J ++））
    做
       回声$ {INDATA [$ i] [$ J]}
    DONE
DONE
 

解决方案

Bash有多维数组的支持。尝试

  =阵列（A B C D）
回声$ {数组[1]}
回声$ {数组[1] [3]}
回声$ {数组[1]退出}
 

有关技巧如何模拟它们，请参阅高级bash脚本编程指南。

I'm attempting to read an input file line by line which contains fields delimited by periods. I want to put them into an array of arrays so I can loop through them later on. The input appears to be ok, but 'pushing' that onto the array (inData) doesn't appear to be working.

The code goes :

Input file: 
GSDB.GOSALESDW_DIST_INVENTORY_FACT.MONTH_KEY
GSDB.GOSALESDW_DIST_INVENTORY_FACT.ORGANIZATION_KEY


infile=${1}

OIFS=$IFS
IFS=":"

cat ${infile} | while read line
do
      line=${line//\./:}
      inarray=(${line})
#      echo ${inarray[@]}
#      echo ${#inarray[@]}      
#      echo ${inarray[0]}
#      echo ${inarray[1]}
#      echo ${inarray[2]}

      inData=("${inData[@]}" "${inarray[@]}")
done 
IFS=$OIFS

echo ${#inData[@]}   

for ((i = 0; i < ${#inData[@]}; i++))
do
 echo $i
    for ((j = 0; j < ${#inData[$i][@]}; j++))
    do
       echo ${inData[$i][$j]}
    done
done

解决方案

Bash has no support for multidimensional arrays. Try

array=(a b c d)
echo ${array[1]}
echo ${array[1][3]}
echo ${array[1]exit}
