Reading multiple files and operating on stored Arrays
Clash Royale CLAN TAG#URR8PPP
I have 2 text files "$LinkP" and "$QuestionP. I want to read these files and store each complete line in the respective array,
IFS=$'rn' GLOBIGNORE='*' command eval "LinkA=($(cat "$LinkP"))"
IFS=$'rn' GLOBIGNORE='*' command eval "QuestionA=($(cat "$QuestionP"))"
Now I want to operate on these using a for loop
nLink=$#LinkA[@] # Size of array
for ((i = 0; i < nLink; i = i + 1)); do
echo $i
Question=$QuestionA[i]
echo "Question=$QuestionA[i]"
done
But, the Question variable doesn't contains full line, it breaks after each space character.
How can I store each question and link (complete line in respective file) in these variable and process them inside for loop.

store each complete line in the respective array
is easy with a different approach:
mapfile LinkA < "$LinkP"
See help mapfile for more options, such as -t to remove a trailing delimiter from each line.
