重擊數組操作

Question

我正在為Unix / Linux類做一個項目，並且在另一個文件中有一些數組，像這樣

所有數組應存儲為1或0

    T1=( 1 1 1 1 1 )
    T2=( 1 1 1 1 1 )
    T3=( 1 1 1 1 1 )
    T4=( 1 1 1 1 1 )
    T5=( 1 1 1 1 1 )

但是我很難將數組編輯為0並進行更改

    #!/bin/bash

    i=0

    for line in `cat JeopardyOut`
    do
        let i=i+1
        #Creating one big Array with all the values from the arrays file
        Array[i]=$line
    done

    cat JeopardyOut

    #Parsing the giant Array into the main 5 arrays I'm using
    createArray()
    {
    y=0
    for y in 0 1 2 3 4
    do
         for i in 2 3 4 5 6
         do
            #echo "${Array[i]}"
            T1[$y]=${Array[i]}
         done

         for i in 9 10 11 12 13
         do
            #echo "${Array[i]}"
            T2[$y]=${Array[i]}
         done

         for i in 16 17 18 19 20
         do
            #echo "${Array[i]}"
            T3[$y]=${Array[i]}
         done

         for i in 23 24 25 26 27
         do
            #echo "${Array[i]}"
            T4[$y]=${Array[i]}
         done

         for i in 30 31 32 33 34
         do
            #echo "${Array[i]}"
            T5[$y]=${Array[i]}
         done

    done
    }

    createArray

    ArrayNum=$1
    Index=$2

可能有更好的方法可以做到這一點，但這最終對我有用。

      #Changing the necessary indexes, this will be used by a completely 
      #different script 
      ChangeArray()
      {

       if [[ $ArrayNum == "1" ]]; then
           T1[ $Index ]=0
      elif [[ $ArrayNum == "2" ]]; then
           T2[ $Index ]=0
      elif [[ $ArrayNum == "3" ]]; then
           T3[ $Index ]=0
      elif [[ $ArrayNum == "4" ]]; then
           T4[ $Index ]=0
      elif [[ $ArrayNum == "5" ]]; then
           T5[ $Index ]=0
      else
            echo "Invalid Parameters"
       fi
  } 

 if [[ $ArrayNum -ne "" || $Index -ne "" ]]; then
    if [[ $ArrayNum == "5" && $Index == "5"]]; then
         reset
    else
         ChangeArray
    fi 
 fi
   # And the part that's likely at fault for my issue but don't know how I 
   # should fix it
   echo "T1=( ${T1[*]} )" > JeopardyOut
   echo "T2=( ${T2[*]} )" >> JeopardyOut
   echo "T3=( ${T3[*]} )" >> JeopardyOut
   echo "T4=( ${T4[*]} )" >> JeopardyOut
   echo "T5=( ${T5[*]} )" >> JeopardyOut

   cat JeopardyOut

我嘗試編輯數組的方式出了點問題...雖然我可以將任何數組的任何索引都設為0，但是我不知道為什么我重新運行腳本時將更改為0的1變為1 。

PS。 這是Sierra中Linux編程的基礎類，除了我通過反復試驗中學到的知識之外，我對其他bash腳本的了解並不多。

也許這個例子可以幫助你

#!/bin/bash

while read -r line; do
    #Creating one big Array with all the values from the arrays file
    Array+=(`grep -oP '\(\K(.+?)(?=\))' <<< "$line"`)
done < JeopardyOut

echo "Giant Array value: ${Array[@]}"

# Or you can clone the arrays in the file

i=0
while read -r line; do
    ((i++))
    eval "T$i=(`grep -oP '\(\K(.+?)(?=\))' <<< "$line"`)"
done < JeopardyOut

echo "This is the contents of array T1: ${T1[@]}"
echo "This is the contents of array T2: ${T2[@]}"
echo "This is the contents of array T3: ${T3[@]}"
echo "This is the contents of array T4: ${T4[@]}"
echo "This is the contents of array T5: ${T5[@]}"

# This can help you to make a new file
# I change some value to our arrays

T1[2]=0
T2[1]=true

# Now let's go to make a new arrays file

echo "T1=(${T1[@]})" > JeopardyOut2
echo "T2=(${T2[@]})" >> JeopardyOut2
echo "T3=(${T3[@]})" >> JeopardyOut2
echo "T4=(${T4[@]})" >> JeopardyOut2
echo "T5=(${T5[@]})" >> JeopardyOut2

echo "This is the content of JeopardyOut2:"

cat JeopardyOut2

Giant Array value: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
This is the contents of array T1: 1 1 1 1 1
This is the contents of array T2: 1 1 1 1 1
This is the contents of array T3: 1 1 1 1 1
This is the contents of array T4: 1 1 1 1 1
This is the contents of array T5: 1 1 1 1 1
This is the content of JeopardyOut2:
