Unable to copy file in Array : Shell Script

Question

#!/bin/sh

i=0


while read line
do 

    for WORD in $line
    do
        #copy to array
    array[$i]=$WORD
    i=$((i+1))
    done

done < ACTION_TAG.txt

File is saved with name .sh

I am trying to copy a file in array. it throws below error.

read.sh: 44: array[0]=sg: not found
read.sh: 44: array[1]=sg: not found
read.sh: 44: array[2]=sg: not found
read.sh: 44: array[3]=sg: not found
read.sh: 44: array[4]=sg: not found
read.sh: 44: array[5]=sg: not found
read.sh: 44: array[6]=sg: not found
read.sh: 44: array[7]=sg: not found
read.sh: 44: array[8]=sg: not found
read.sh: 44: array[9]=sg: not found
read.sh: 44: array[10]=sg: not found
read.sh: 44: array[11]=sg: not found
read.sh: 44: array[12]=sg: not found
read.sh: 44: array[13]=sg: not found
read.sh: 44: array[14]=sg: not found
read.sh: 44: array[15]=sg: not found

I went through the same queries posted on stackoverflow but was unable to solve problem. can some one help.

I have just tested this code with some sample text and it worked as expected, could you provide some sample text from the file that causes the error? — scragar

my code was exactly the same as yours, the only things I can think that might be different is your input file or that I use BASH as my shell(most people prefer zsh or ksh because they're faster). — scragar

You are using wrong shebang here #!/bin/sh If you want to use BASH array then use:

#!/bin/bash

Also to store various words in array you can use this much simplified script:

#!/bin/bash

array=()
while read line
do 
    array+=( $line )
done < ACTION_TAG.txt

You need to make sure to run this script as bash ./script.sh
